Subject: closes bpo-13497: Fix `broken nice` configure test. (GH-12041)
X-Git-Tag: v3.7.3rc1~44
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=2055ebb940a737b1375435209c37eae535f062f9;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)
