It seems defined in /usr/share/autoconf/autoconf/c.m4
where you have:
CXXFLAGS="-g"
AC_CACHE_CHECK(whether $CXX accepts -g, ac_cv_prog_cxx_g,
[_AC_COMPILE_IFELSE([AC_LANG_PROGRAM()],
[ac_cv_prog_cxx_g=yes],
[ac_cv_prog_cxx_g=no])])
if test "$ac_test_CXXFLAGS" = set; then
CXXFLAGS=$ac_save_CXXFLAGS
elif test $ac_cv_prog_cxx_g = yes; then
if test "$GXX" = yes; then
CXXFLAGS="-g -O2"
else
CXXFLAGS="-g"
fi
fi[]dnl
I would expect no "-g" by default as well, and to be able to tell configure
use "-g" with e.g. an argument "enable-debug".
