Eric, Gerald, all,
I have now committed (Rev. 200360) the attached patch. (Compared to the
draft patch, with a missing "," added in AC_CHECK_TYPES).
Eric, Gerald: Can you confirm that it now works on both FreeBSD and Solaris?
Eric: Should one (conditionally) include <floatingpoint.h> on Solaris? I
am asking because LIBGFOR_CHECK_FPSETMASK in acinclude.m4 uses that
include file during configure - but libgfortran.h (or config/fpu-sysv.h)
don't.
