Hmm, that might not be in the docs as such, it's just that you can
reassign most of @xxFLAGS@ seen in your Makefile.in while being in
the configure.ac and before AC_OUTPUT. Just use shell-syntax for
that like
xxFLAGS="$xxFLAGS $myFLAGS"
hmmm, I'm not sure whether the autoconf manual should carry a section
on usual constructs of shell programming. AFAIK, it would help simply
because shell programming is not the common skill among (younger)
developers anymore since there are other and more powerful scripting
languages available and also installed in a usual system.
