+# FP_GCC_EXTRA_FLAGS
+# ------------------
+# Determine which extra flags we need to pass gcc when we invoke it
+# to compile .hc code.
+#
+# Some OSs (Mandrake Linux, in particular) configure GCC with
+# -momit-leaf-frame-pointer on by default. If this is the case, we
+# need to turn it off for mangling to work. The test is currently a
+# bit crude, using only the version number of gcc.
+#
+# -fwrapv is needed for gcc to emit well-behaved code in the presence of
+# integer wrap around. (Trac #952)
+#
+# -fno-unit-at-a-time or -fno-toplevel-reoder is necessary to avoid gcc
+# reordering things in the module and confusing the manger and/or splitter.
