From e6783c99f051c6d8252db5f388d805cef0e16357 Mon Sep 17 00:00:00 2001 From: Joshua Watt Date: Thu, 20 Feb 2020 15:20:45 -0600 Subject: [PATCH] build: Fix strndup detection on MinGW GCC and meson conspire together to incorrectly detect that strndup() exists on MinGW as __builtin_strndup, when no such function exists. As a work around, meson will skip looking for __builtin functions if an '#include' is in the prefix, so add '#include ' when looking for strndup().
