[Octave-bug-tracker] [bug #48319] Development source build failure related to LONG_DOUBLE_ROUNDING in oct-inttypes.cc

[Mike Miller]

Follow-up Comment #9, bug #48319 (project octave):

I think jwe was referring to #including libgnu/fpucw.h in oct-inttypes.cc
instead of pasting the relevant macros like the patch does.

I had a suggestion to define wrapper functions for these instructions, but
that would add undesired overhead to these calls which should be very simple
and fast.

What if we made it explicit by declaring it as


#include "libgnu/fpucw.h"


to mark it as a gnulib header file being used intentionally. This is not a
header file that masks other standard library header files, so it's a
different case. That would also make it searchable and identifiable for future
maintenance.
