Subject: closes bpo-13497: Fix `broken nice` configure test. (GH-12041)
X-Git-Tag: v2.7.17rc1~145
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=a0f656d310bdd08aaaa6f1e186bc7a4174e4068f;p=thirdparty%2FPython%2Fcpython.git

closes bpo-13497: Fix `broken nice` configure test. (GH-12041)


Per POSIX, `nice(3)` requires `unistd.h` and `exit(3)` requires `stdlib.h`.

Fixing the test will prevent false positives with pedantic compilers like clang.
(cherry picked from commit 90c6facebd5666fec85f125ee2795b48b30319a4)
