Release 2.2.9 Wed Septemper 25 2019
        Other changes:
                  examples: Drop executable bits from elements.c
            #349  Windows: Change the name of the Windows DLLs from expat*.dll
                    to libexpat*.dll once more (regression from 2.2.8, first
                    fixed in 1.95.3, issue #61 on SourceForge today,
                    was issue #432456 back then); needs a fix due
                    case-insensitive file systems on Windows and the fact that
                    Perl's XML::Parser::Expat compiles into Expat.dll.
            #347  Windows: Only define _CRT_RAND_S if not defined
                  Version info bumped from 7:10:6 to 7:11:6

        Special thanks to:
            Ben Wagner

Release 2.2.8 Fri Septemper 13 2019
        Security fixes:
       #317 #318  CVE-2019-15903 -- Fix heap overflow triggered by
                    XML_GetCurrentLineNumber (or XML_GetCurrentColumnNumber),
                    and deny internal entities closing the doctype;
                    fixed in commit c20b758c332d9a13afbbb276d30db1d183a85d43

        Bug fixes:
            #240  Fix cases where XML_StopParser did not have any effect
                    when called from inside of an end element handler
            #341  xmlwf: Fix exit code for operation without "-d DIRECTORY";
                    previously, only "-d DIRECTORY" would give you a proper
                    exit code:
                      # xmlwf -d . <<<'<not well-formed>' 2>/dev/null ; echo $?
                      2
                      # xmlwf <<<'<not well-formed>' 2>/dev/null ; echo $?
                      0
                    Now both cases return exit code 2.

        Other changes:
       #299 #302  Windows: Replace LoadLibrary hack to access
                    unofficial API function SystemFunction036 (RtlGenRandom)
                    by using official API function rand_s (needs WinXP+)
            #325  Windows: Drop support for Visual Studio <=7.1/2003
                    and document supported compilers in README.md
            #286  Windows: Remove COM code from xmlwf; in case it turns
                    out needed later, there will be a dedicated repository
                    below https://github.com/libexpat/ for that code
            #322  Windows: Remove explicit MSVC solution and project files.

# Expat, Release 2.2.5

This is Expat, a C library for parsing XML, started by
[James Clark](https://en.wikipedia.org/wiki/James_Clark_(programmer)) in 1997.
Expat is a stream-oriented XML parser.  This means that you register
handlers with the parser before starting the parse.  These handlers
are called when the parser discovers the associated structures in the
document being parsed.  A start tag is an example of the kind of
structures for which you may register handlers.






Windows users should use the
[`expat_win32` package](https://sourceforge.net/projects/expat/files/expat_win32/),
which includes both precompiled libraries and executables, and source code for
developers.

Expat is [free software](https://www.gnu.org/philosophy/free-sw.en.html).
................................................................................
When using Expat with a project using autoconf for configuration, you
can use the probing macro in `conftools/expat.m4` to determine how to
include Expat.  See the comments at the top of that file for more
information.

A reference manual is available in the file `doc/reference.html` in this
distribution.

# Expat, Release 2.2.9

This is Expat, a C library for parsing XML, started by
[James Clark](https://en.wikipedia.org/wiki/James_Clark_(programmer)) in 1997.
Expat is a stream-oriented XML parser.  This means that you register
handlers with the parser before starting the parse.  These handlers
are called when the parser discovers the associated structures in the
document being parsed.  A start tag is an example of the kind of
structures for which you may register handlers.

Expat supports the following compilers:
- GNU GCC >=4.5
- LLVM Clang >=3.5
- Microsoft Visual Studio >=8.0/2005

Windows users should use the
[`expat_win32` package](https://sourceforge.net/projects/expat/files/expat_win32/),
which includes both precompiled libraries and executables, and source code for
developers.

Expat is [free software](https://www.gnu.org/philosophy/free-sw.en.html).
................................................................................
When using Expat with a project using autoconf for configuration, you
can use the probing macro in `conftools/expat.m4` to determine how to
include Expat.  See the comments at the top of that file for more
information.

A reference manual is available in the file `doc/reference.html` in this
distribution.


The CMake build system is still *experimental* and will replace the primary
build system based on GNU Autotools at some point when it is ready.
For an idea of the available (non-advanced) options for building with CMake:

```console
# rm -f CMakeCache.txt ; cmake -D_EXPAT_HELP=ON -LH . | grep -B1 ':.*=' | sed 's,^--$,,'
// Choose the type of build, options are: None Debug Release RelWithDebInfo MinSizeRel ...
CMAKE_BUILD_TYPE:STRING=

// Install path prefix, prepended onto install directories.
CMAKE_INSTALL_PREFIX:PATH=/usr/local

// Path to a program.
DOCBOOK_TO_MAN:FILEPATH=/usr/bin/docbook2x-man

// build man page for xmlwf
EXPAT_BUILD_DOCS:BOOL=ON

// build the examples for expat library
EXPAT_BUILD_EXAMPLES:BOOL=ON

// build fuzzers for the expat library
EXPAT_BUILD_FUZZERS:BOOL=OFF

// build the tests for expat library
EXPAT_BUILD_TESTS:BOOL=ON

// build the xmlwf tool for expat library
EXPAT_BUILD_TOOLS:BOOL=ON

// Character type to use (char|ushort|wchar_t) [default=char]
EXPAT_CHAR_TYPE:STRING=char

// install expat files in cmake install target
EXPAT_ENABLE_INSTALL:BOOL=ON

// Use /MT flag (static CRT) when compiling in MSVC
EXPAT_MSVC_STATIC_CRT:BOOL=OFF

// build a shared expat library
EXPAT_SHARED_LIBS:BOOL=ON

// Treat all compiler warnings as errors
EXPAT_WARNINGS_AS_ERRORS:BOOL=OFF

// Make use of getrandom function (ON|OFF|AUTO) [default=AUTO]
EXPAT_WITH_GETRANDOM:STRING=AUTO

// utilize libbsd (for arc4random_buf)
EXPAT_WITH_LIBBSD:BOOL=OFF

// Make use of syscall SYS_getrandom (ON|OFF|AUTO) [default=AUTO]
EXPAT_WITH_SYS_GETRANDOM:STRING=AUTO
```

 * _Expat_LoadLibrary()
 *
 * This is used to dynamically load DLLs using the most secure method available
 * for the version of Windows that we are running on.
 *
 * Parameters:
 *
 * filename  [in] - The filename or full path of the DLL to load. If only the
 *                  filename is passed then the DLL will be loaded from the
 *                  Windows system directory.
 *
 * Returns the handle of the module on success; otherwise NULL.
