+Subject: [PATCH] Use default cc from environment variable
+
+In case the system uses a custom c compiler instead of cc
+(e.g. for cross-compiling), probing system features can
+fail or can misidentify the features due to the incorrect C compiler.
+
+Instead of using only "cc" for probing features, check if the CC environment
+variable has a custom C compiler set. If it is present, use that instead of
+"cc". If it is not present, fall back to "cc".
+
+Upstream-Status: Submitted [https://github.com/osvenskan/posix_ipc/pull/56]
