--no-ansi (mgnuc) and --no-ansi-c (mmc) have not actually done anything for
many years now. Deprecate these options and remove their "use" throughout most
of the Mercury system. (The remaining uses are in the Makefiles for the Boehm
GC, which need to be updated separately.)
Also deprecate the internal compiler option --cflags-for-ansi.
compiler/options.m:
Document that --no-ansi-c is now deprecated.
Document that the internal option --cflags-for-ansi is now
deprecated.
compiler/compile_target_code.m:
Do not pass the ANSI options to the C compiler.
scripts/mgnuc.in:
scripts/mgnuc_file_opts.sh-subr:
Deprecate the --no-ansi option; delete code that no longer does
anything useful.
configure.ac:
Delete the configuration variable CFLAGS_FOR_ANSI; it is only ever
set to be empty. (The comment talks about --no-ansi doing other things
in the mgnuc script. It used to also cause some preprocessor macros
to be defined for compatibility with the system headers on some
platforms -- that has not been the case since 2013.)
doc/user_guide.texi:
Document that --no-ansi-c is deprecated.
