Hello everyone,
I wasn't sure if I needed approval for this patch or not, but better

I've just installed the patch, but if you find the need for any further
improvement, let me know and I'll do it right away.

Hi,
the gcc_AC_FUNC_MMAP_BLACKLIST function in gcc/acinclude.m4 is exactly the

Hi,
this is version 2 of the patch.
The initial problem is that libgfortran configure.ac used AC_CHECK_LIB([m]…)
to check wether several math functions are available. That doesn't work on
