--- Comment #47 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Does mingw/cygwin always use GNU binutils? At least for ld.bfd, a quick and reliable test could be $gcc_cv_ld --verbose 2>&1 | grep -q '\.debug_loclists.*BLOCK.*__section_alignment__.*NOLOAD.*:' && $gcc_cv_ld --verbose 2>&1 | grep -q '\.debug_rnglists.*BLOCK.*__section_alignment__.*NOLOAD.*:' or so in configure.ac (for mingw/cygwin only, and AC_DEFINE a macro in that case).
