Comment(by Snark):
I'm trying to track down the numerical glitches related to the lgammal
libm(in glibc) implementation, as discussed on the ubuntu glibc
[https://bugs.launchpad.net/ubuntu/+source/eglibc/+bug/713985 ticket], as
fixing the problem upstream looks like a better option in that case.
So far, I think I tracked down the implementation in either in
sysdeps/ieee754/ldbl-128/e_lgammal_r.c or
sysdeps/ieee754/ldbl-96/e_lgammal_r.c. The problem is that I don't know
which is compiled in, as I don't even see those in any Makefile!
