I have a section of my configure.ac that tries to guess values for
CPPFLAGS, etc.
I also have an option --disable-flag-setting to turn this off
entirely.
Sometimes my configure wants to set a flag, but the user wants to try
a contradictory flag. So I allow a way to stop the configure from
messing with the flags, so that the user can take complete control if
need be.
