Sounds reasonable. You could also overload the existing speex_*_ctl() calls
to take SPEEX_GET_LIB_VERSION, SPEEX_GET_LIB_MAJOR_VERSION, etc.

What people are really asking for here is a way to determine at for conditional
compilation (i.e. at configure time) what calls are available. One traditional
way to do that is just to provide #defines for SPEEX_MAJOR_VERSION and so
on in the header. If you're using autoconf you can of course try to link with
one of the new functions, but just saying:

#include <speex.h>

#if defined(SPEEX_MINOR_VERSION) && (SPEEX_MINOR_VERSION > 0)
  /* code that uses speex_decode_int(); */
#else
  /* code that uses speex_decode(); */
#endif

is more portable. So it might be worth doing that as well.

FWIW,
