Fortran: Allow IEEE_CLASS to identify signaling NaNs
We use the issignaling macro, present in some libc's (notably glibc),
when it is available. Compile all IEEE-related files in the library
(both C and Fortran sources) with -fsignaling-nans to ensure maximum
compatibility.
libgfortran/ChangeLog:
PR fortran/82207
* Makefile.am: Pass -fsignaling-nans for IEEE files.
* Makefile.in: Regenerate.
* ieee/ieee_helper.c: Use issignaling macro to recognized
signaling NaNs.
gcc/testsuite/ChangeLog:
PR fortran/82207
* gfortran.dg/ieee/signaling_1.f90: New test.
* gfortran.dg/ieee/signaling_1_c.c: New file.
