I will not argue that the function is deprecated.

NTL i added the gamma_r function that are missing
and changed the wording for the description. I think
it is better than in lgamma especially  for signgam.
I noticed that it should be more obvious.

I just read the manual page about gamma, and those functions/macros are
deprecated (use either lgamma or tgamma instead).  As far as I can read,
those alternative functions have all the functionality one can need, so
I guess there's zero reasons to use gamma at all, which is a misleading
alias for lgamma.  I think I won't patch that page at all.

The glibc source code itself has a comment saying that gamma macros are
obsolete:

[
#if defined __USE_MISC || (defined __USE_XOPEN && !defined  __USE_XOPEN2K)
# if !__MATH_DECLARING_FLOATN
/* Obsolete alias for `lgamma'.  */
__MATHCALL (gamma,, (_Mdouble_));
# endif
#endif
]

Thanks,

Alex
