 # 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.
-# (eg. Trac #1427)
