And libgomp-5.1.1

Here's what's installed from gcc:

cpp-5.1.1-4.fc22.x86_64
gcc-5.1.1-4.fc22.x86_64
gcc-c++-5.1.1-4.fc22.x86_64
libgcc-5.1.1-4.fc22.x86_64
libgfortran-5.1.1-4.fc22.x86_64
libgomp-5.1.1-4.fc22.x86_64
libquadmath-5.1.1-4.fc22.x86_64
libstdc++-5.1.1-4.fc22.x86_64
libstdc++-devel-5.1.1-4.fc22.x86_64

It seems gcc is not going to fix this:

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=65467

I tried building with -std=c99 and -std=c90. Both gave same error.
