--- Comment #1 from Matthias Klose <doko at gcc dot gnu.org> ---
didn't check a configuration with --disable-shared :-/ What about checking for
a $bdw_lib_dir/libgc.la and in that case setting BDW_GC_LIBS to
$bdw_lib_dir/libgc.la and skipping the compile and link tests? I assume we
could do a file check for the header file as well for this case.
