+Subject: [PATCH 06/12] configure.ac: remove --enable-debug flag.
+
+The --enable-debug flag only does two things at the moment:
+
+  1. It adds "-O" (as opposed to "-O2") to your CXXFLAGS and FCFLAGS.
+  2. It adds "-g" to your CXXFLAGS and FCFLAGS.
+
+When using gcc and gfortran, this is a convenient way to enable those
+debugging flags. However, those options are not guaranteed to be
+supported by other compilers. In the interest of simplicity and
+portability, this commit simply removes the flag.
+
+It would of course be possible to compile two test programs with
+CXXFLAGS="-g -O" and FCFLAGS="-g -O" to determine whether or not those
+flags are supported. That would solve half of the problem, but would
+be a no-op (that is, it would not enable any debugging features) on
+systems where the flags are not supported. That problem is more
+difficult to solve, and hints that it's best to leave specific
+compiler flags out of the build system whenever possible.
