+    #   -Waggregate-return -- This seems to be a performance-related warning
+    #       aggregate return values are legal in ANSI C, but they may be returned
+    #       in memory rather than through a register.  We do use aggregate return
+    #       values, but they are structs of a single basic type (used to enforce
+    #       type checking for relative vs. absolute ptrs), and with optimization
+    #       the aggregate value is converted to a scalar.
     # the embedded newlines in this string are safe because we evaluate each
     # argument in the for-loop below and append them to the CFLAGS with a space
