Different *CFLAGS in gcc/Makefile.in


Hello All,

in gcc/Makefile.in there are many different *CFLAGS, notablye

ALL_CFLAGS = $(X_CFLAGS) $(T_CFLAGS) \
$(CFLAGS) $(INTERNAL_CFLAGS) $(COVERAGE_FLAGS) $(WARN_CFLAGS) $(XCFLAGS) @DEFS@


Do anyone have a precise idea of what all these *CFLAGS are exactly for?
(I guessed a bit some of them, but I'm not sure to be able to explain...)

Maybe we might add a few lines of comments there?


Regards
