--- Comment #1 from Robert Dubner <rdubner at gcc dot gnu.org> ---
I finally got around to looking at this.
The inclusion of -f-no-strict-aliasing was edited into libgcobol/Makefile.am by
Iain Sandoe:
b90364ee1c09 (Iain Sandoe 2025-03-22 16:58:47 +0000 94) AM_CXXFLAGS +=
-fno-strict-aliasing
I have to assume that this is part of Iain's efforts to compile on an Apple
Darwin OS.
I hope Iain can comment. Perhaps, if it is necessary, the -fno-strict-aliasing
switch can be tucked into an IF DARWIN conditional.
I did the following as an experiment, and it didn't seem to have any ill
effects on an x86_64 build:
