Hi Eric, I think it is worth applying this patch before you release m4. Without it the tarball will likely fail to build due to linker errors on platforms other than GNU/Linux.
Also, while there, updating @INTL_MACOSX_LIBS@, per Bruno's recommendations [1]. With the fix so 'make syntax-check' works. Collin [1] https://lists.gnu.org/archive/html/bug-gnulib/2025-03/msg00001.html
