--- Comment #18 from Jerry DeLisle <jvdelisle at gcc dot gnu.org> --- Created attachment 33227 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=33227&action=edit A preliminary patch This patch is preliminary for "proof of principle". If the idea is acceptable, then configuration magic is required to ensure the locale.h is available, and if not, default to '.'.
