A side effect of this patch is that AC_PROG_CXX now AC_SUBSTs
CCC. Is this really meant ? As far as I can tell, this
variable is documented as being read to set CXX; it is not
documented as an output variable, and I don't think we want
people to use it in Makefile.ins.
(I just noticed that because this new variable matched a pattern
in an Automake test case and caused it to fail. Blame those
grepish test cases...)
