+# In GCC 4.4.7, the compiler gripes about shadowed global
+# declarations when a local variable uses the name of a
+# function that's in a system header file.  For some reason,
+# later versions of GCC (e.g., 5.2.0) don't complain about
+# the shadowed globals.  Maybe later versions are less fussy?
+# Anyway, the shadowing seems to be harmless, and GCC 4.4.7
+# is not a supported compiler, so let us promote shadowed globals
+# warnings to errors only for GCC 5 and later.
