tgamma function in math library

Perhaps you could write a wrapper called gamma() that does something like this:

=====
struct    utsname *ub;
/* malloc, etc. */

if(uname(ub)) {
    die();
}
if (strcmp(ub->sysname, "Linux") {
   tgamma();
} else {
   gamma();
}
That's wont work - you can't call the wrapper "gamma" as well.

Either use configure, or hardcode it:

#ifdef __GLIBC__
#define gamma(x) tgamma(x)
#endif
and then use gamma() normally.
