Subject: [PATCH] Add clang suport as build cc
|
|
|
|
ccforbuild.m4 comes from gmp project (very old version).
|
|
Current version does not support clang due to using GCC exit()
|
|
builtin function. clang does not have exit() builtin function.
|
|
|
|
GMP project fixed this issue by the commit https://gmplib.org/repo/gmp/rev/beda46a3c10d
|
|
|
|
This patch backports "upstream" change (`exit(0)` relaced by
|
|
`return 0` in conftest.c)
