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!

just in case: as the root, do the following: 1) add the line
{{{
deb-src http://ports.ubuntu.com/ubuntu-ports/ oneiric main restricted
universe
}}}
to /etc/apt/sources.list
2) at the shell prompt
{{{
apt-get install devscripts
apt-get build-dep eglibc
apt-get source eglibc
cd eglibc-2.13/
}}}
now you can edit the source as you please. Then, in eglibc-2.13/
{{{
debuild -us -uc
}}}
builds the library creates .deb file(s) in ../.
Probably there will be a library to link against in eglibc-2.13/, to test
things.
Else, one can just
{{{
cd ..
dpkg --install eglibc-2.13.deb
}}}
and then compile/link as usual.
