+Subject: [PATCH] Fix CC logic in configure
+
+In https://github.com/madler/zlib/commit/e9a52aa129efe3834383e415580716a7c4027f8d,
+the logic was changed to try check harder for GCC, but it dropped
+the default setting of cc=${CC}. It was throwing away any pre-set CC value as
+a result.
+
+The rest of the script then cascades down a bad path because it's convinced
+it's not GCC or a GCC-like compiler.
+
+This led to e.g. misdetection of inability to build shared libs
+for say, multilib cases (w/ CC being one thing from the environment being used
+for one test (e.g. x86_64-unknown-linux-gnu-gcc -m32 and then 'cc' used for
+shared libs (but missing "-m32"!)). Obviously just one example of how
+the old logic could break.
+
+This restores the old default of 'CC' if nothing overrides it later
+in configure.
