May I respectfully suggest something a bit more organised and less chaotic
1) A *RUNTIME* call into the library which returns an unsigned long (32-bit)
value split up as follows:
^^ release level [alpha, beta, gamma, release, post-release patch#]
^^ minor version
^^^^ major version
You can partition the release level as follows:
00-2F = pre-alpha
30-4F = alpha
50-6F = beta
70-7F = gamma
80-FF = release
1.1b17 would be: 0x00010161
2.2.35 would be: 0x000202A3
Then you can define compile-time MACROS for
#define SPEEX_GET_FULL_VERSION (speex_lib_version())
#define SPEEX_GET_MAJOR_MINOR_VERSION (speex_lib_version() >> 24)
#define SPEEX_GET_MAJOR_VERSION (speex_lib_version() >> 16)
#define SPEEX_GET_RELEASE_LEVEL (speex_lib_version() & 0xFFUL)
#define SPEEX_GET_FULL_MINOR_VERSION (speex_lib_version() & 0xffffUL)
#define SPEEX_GET_MINOR_VERSION ((speex_lib_version() >> 8) & 0xFFUL)
2) A *RUNTIME* call into the library which returns the text-version string
of the library in use.
