Well, I get further into the compile process, but now it fails on
another gcc compile operations. This is essentially the same error
message I was getting before. It tries to #include <fenv.h>, but does
not find it (it shouldn't be including it anyway, as you said). This
time it fails when trying to compile "_capi.c". Thanks for all your
help so far!
