I thought we decided the main problem was that GCC 15 defaults to C23 and GMP needs to explicitly specify like C17 or C11. But if they are fixing it so it compiles with C23, that's an acceptable solution.

RTEMS also somehow has never specified a -std argument. I should have an MR up which specifies the C version and -D arguments to enable POSIX and GNU functions.
