[Bug fortran/32980] New: Vendor extension: Intrinsic functions (D)GAMMA, LGAMMA (ALGAMA/DLGAMA)

["burnus at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

It would be useful if gfortran could implement the following two intrinsics:

a) The Gamma function GAMMA, specific name DGAMMA
b) The logarithm of the Gamma function LGAMMA, specific names ALGAMA, DLGAMA

They are supported by a couple of compilers such as g95, xlf95.

It would be nice if the manual could contain also the definition (integral).
