The important point is that gamma_r and gammaf_r are exported by Cygwin
and must be kept available, otherwise building the DLL fails.  If they
returned the wrong vaslue, that's a bug and needs fixing.

Whether gamma_r and gammaf_r are still functions on their own, or if
they are just defined as aliases to lgamma_r and lgammaf_r in
winsup/cygwin/common.din, as in

  gamma_r = lgamma_r NOSIGFE
  gammaf_r = lgammaf_r NOSIGFE

is up to you.
