--- Comment #20 from Gaius Mulley <gaius at gcc dot gnu.org> --- Created attachment 56558 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=56558&action=edit Proposed fix (libgm2/acinclude.m4 and libgm2/configure.host) Here is a proposed patch for a new file libgm2/acinclude.m4 and libgm2/configure.host. These were taken from libstdc++-v3 and heavily pruned. I've seen it bootstrap under netbsd, freebsd, aarch64 linux, x86_64 linux. acinclude.m4 provides the missing autoconf functions.
