Re: [fortran, patch] IEEE intrinsic modules (ping)

I apologize. Thanks for checking in the fix.

That’s weird, especially if that one fails but ieee_rounding_1.f90 works. Let me know if I can do anything to help debug this.

Actually, it makes a lot of sense to change these into static assertions: this way, any target-specific issues with FP-state buffer size will show up at libgfortran-building-time, rather than be swept under the rug.

Since libgfortran is compiled with GCC, which supports _Static_assert since 4.6, I propose the attached patch.
Built and tested on x86_64-linux, OK to commit?
