From ee3925486f3567b9fe45cb98a88b9acc64991127 Mon Sep 17 00:00:00 2001 From: Leah Rowe Date: Tue, 29 Apr 2025 21:15:22 +0100 Subject: [PATCH 1/1] crossgcc/gmp: Add upstream fix for GCC 15 See: https://gmplib.org/list-archives/gmp-devel/2025-January/006279.html by default, upstream GCC-15 now defaults to -std=c23, instead of -std=c17, which can cause some build issues. GMP has this patch on their mailing list for GCC-15 (see link).
