27    # getting rid of the -g (which I don't think is needed for a production
28    # library). This fudge seems to achieve the necessary. First, we remember the
29    # externally set values of CFLAGS and CXXFLAGS. Then call the AC_PROG_CC and
30    # AC_PROG_CXX macros to find the compilers - if CFLAGS and CXXFLAGS are not
31    # set, they will be set to Autoconf's defaults. Afterwards, if the original
32    # values were not set, remove the -g from the Autoconf defaults.
