Michael Felt <aixto...@felt.demon.nl> added the comment: Actually, iirc - xlc is c99 plus a few extra settings.
The configuration files for xlc are, traditionally, in /etc (the later versions of the compiler have moved them into /opt/show/where so that multiple versions of the compiler can be installed. buildbot@x064:[/home/buildbot]ls -l /etc/*vac* -rw-r--r-- 1 bin bin 37731 Aug 02 2018 /etc/vac.cfg.53 -rw-r--r-- 1 bin bin 39672 Aug 02 2018 /etc/vac.cfg.61 -rw-r--r-- 1 bin bin 39681 Aug 02 2018 /etc/vac.cfg.71 -rw-r--r-- 1 bin bin 39611 Aug 02 2018 /etc/vac.cfg.72 Herein I see that xlc is "extc99" and some extras: * -qlanglvl=extc99 C compiler with common extensions, UNIX headers xlc: use = DEFLT_C crt = /lib/crt0.o mcrt = /lib/mcrt0.o gcrt = /lib/gcrt0.o libraries = -L/usr/vac/lib,-lxlopt,-lxlipa,-lxl,-lc proflibs = -L/lib/profiled,-L/usr/lib/profiled options = -qlanglvl=extc99,-qcpluscmt,-qkeyword=inline,-qalias=ansi I have chosen the xlc_r variant - for thread_safe additions: * standard c compiler aliased as xlc_r (61 Threads) xlc_r: use = DEFLT_C crt = /lib/crt0.o mcrt = /lib/mcrt0.o gcrt = /lib/gcrt0.o libraries = -L/usr/vac/lib,-lxlopt,-lxlipa,-lxl,-lpthreads,-lc proflibs = -L/lib/profiled,-L/usr/lib/profiled hdlibs = -L/usr/vac/lib,-lhmd options = -qlanglvl=extc99,-qcpluscmt,-qkeyword=inline,-qalias=ansi,-qthreaded,-D_THREAD_SAFE,-D__VACPP_MULTI__ So, what is c99 then? -> focus on it is 'stdc99' rather than 'extc99' * Strict ANSI compiler, ANSI headers c99: use = DEFLT_C crt = /lib/crt0.o mcrt = /lib/mcrt0.o gcrt = /lib/gcrt0.o libraries = -L/usr/vac/lib,-lxlopt,-lxlipa,-lxl,-lc proflibs = -L/lib/profiled,-L/usr/lib/profiled options = -qlanglvl=stdc99,-D_ANSI_C_SOURCE,-D_ISOC99_SOURCE,-qalias=ansi,-qstrict_induction Hope this helps clarify that both xlc and c99 are "c99" based.
