right, but like said, other compilers can generate them, only with a
different CLI switch, and non withstanding this problem, there are tools
to generate such kind of information easily.
Though for those who care about this issue, this is hackable easily
using config.mak, here is how:
CFLAGS += -MMD -MF $(@D)/.$(@F:.o=.dep)
-include $(wildcard .*.dep */.*.dep) GIT-VERSION-FILE
It's a quick hack, but allow gcc + gnu make (I believe $(@D) is GNU)
users not to be bitten hard by those dependency issues.
The reason why I include GIT-VERSION-FILE again is that many make
complain if -include gets an empty like as an argument, and passing
/dev/null on certains occasions triggers warnings about /dev/null having
a date in the future on some machines for a reason I never found.
