dnl The CLN manual says that without CFLAGS or CXXFLAGS being set compilation
dnl will happen with -O.  However, AC_PROG_CC and AC_PROG_CXX set CFLAGS and
dnl CXXFLAGS to "-g -O2", which produces way too large binaries.


dnl Wrapper around AC_PROG_CC setting CFLAGS to plain "-O" as opposed to
dnl "-g -O2" for the GNU compiler (unless CFLAGS was set before).
