This is an annoying warning that GCC always outputs on Cygwin either
32-bit or 64-bit. It's harmless really but it is output for every single
compiled source file--C or fortran--and there is no `-Wno-` flag to
disable it.
There is a patch now in GCC to remove this outright:
https://gcc.gnu.org/ml/gcc-patches/2015-08/msg00836.html But I don't know
when it will be available. The default GCC currently in Cygwin is 5.3,
and it does not have this patch.
It's not worth putting in a lot of effort over this, but I'm squashing it
wherever I see it by just removing the `-fPIC` flag (if possible) on
Cygwin. I will maintain a branch for these changes wherever I come across
them.
