- 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).
- Signed-off-by: Leah Rowe <leah@libreboot.org>

- +Subject: [PATCH 1/1] acinclude.m4: fix -std=c23 build failure

- +Add prototype to configure test function as c23 removes unprototyped
- +functions.

- +gcc-15 switched to -std=c23 by default:

- +As a result `configure` fails with:
- + conftest.c: In function 'f':
- + conftest.c:12:48: error: too many arguments to function 'g'; expected 0, have 6
- + 12 | for(i=0;i<1;i++){if(e(got,got,9,d[i].n)==0)h();g(i,d[i].src,d[i].n,got,d[i].want,9);if(d[i].n)h();}}
