* configure.ac: Rewrite DGUX check to use GC_CFLAGS, and -O0 check
to remove the need for MY_CFLAGS.
* Makefile.am: Do not use @...@ substitutions. Use AM_CXXFLAGS,
AM_CFLAGS and AM_LDFLAGS instead of redefining LTCOMPILE and LINK.
Use "override" to disable -O2 when required.
* configure: Regenerate.
* Makefile.in: Regenerate.
* include/Makefile.in: Regenerate.
