You have to insert your own preprocessor defines - which could be
handled better with autoconf.
It evaluates if the requested feature is available and produces the
output.
See my example with strerror/strerror_r in my previous mail.

(without autoconf)

#if defined (LINUX || Solaris_10)
strerror_r
#elif defined (Solaris_28 || HP/UX_11)
strerror
#else
...

(autoconf - version)

#ifdef HAS_STRERROR_R
strerror_r
#else
strerror
#endif
