Hello, all. It seems that NESTED_FUNC_ATTR strikes again. This time
since most of our devs use gcc >= 4.5 (I use 4.6) where the compiler
bug is fixe, it's a bigger problem than before. So I propose the
following: If gcc has this bug, compile with mregparms=1 and show a
message recommendation to upgrade. Since we may be unable to execute
target programs, we have to rely on version check but it shouldn't cause
much trouble. This way we continue to support gcc < 4.5 without
sacrificing reliability and finally get rid of the need of
NESTED_FUNC_ATTR. The only downside is increased binary size with gcc < 4.5.
