Comment (by vbraun):
The `sage/libs/gap/test/main.c` is only for instructional purposes, it
demonstrates how to build a standalone binary so you can run libGAP under
a debugger/valgrind without Sage. It doesn't exercise anything thats not
already in doctests.
One could add a `spkg-check` to test `src/test` in the spkg, but they
again don't exercise anything thats not covered by libGAP doctests.
I've removed the upstream-gap-x.y.z directories from the spkg, the `make-
spkg.sh` script copied them there accidentally.
Gap links against MPIR just fine, the only issue is with a version check
that I reported here: https://groups.google.com/d/topic/mpir-
devel/X48SfwGkSd8/discussion. This is why the `spkg-install` adds
`-D__GMP_MP_RELEASE=50002` to the `CFLAGS`:
{{{
