(before we misunderstand each other i do not insists on that patch)

The function is available and that should be documented.
They seem available for some time, but glibc says: These functions 
exist for compatibility reasons.

What is about a merger with lgamma() ?

adding to the notes section something like that:
   glibc version
       Glibc  has  a  gamma() function (and _r) that is equivalent to 
       lgamma(3) and computes the natural logarithm of the Gamma function.
       That function is deprecated and should not be used in newer programs.

I never used these functions, so I don know for sure.  Isn't gamma_r(3)
just an (obsolete) alias for lgamma_r(3)?

If so, lgamma_r(3) is already documented, and the gamma(3) manual page
already points to it.  I don't see why gamma_r(3), which is obsolete,
should be documented.

Thanks,

Alex
