+# cpp is set to Apple's cpp. Actually, cpp is merely on-path so Apple's cpp
+# is used. But Apple's cpp is sufficiently different from GNU's cpp and causes
+# Autotools a lot of trouble because Autotools tests are predicated on GNU cpp.
+# If your Autotools project results in "configure:6560: error: C preprocessor
+# cpp fails sanity check", then file a bug report with Autotools.
