Looking at the patch, it defines FORMATL32_MODIFIER for all gcc >= 4.2.
Interestingly, FreeBSD (7.x) uses gcc 4.2.1 and doesn't have any problem
compiling HotSpot (its my main platform). So perhaps this is overly
broad? I'll give the patch a try and see if it causes any compile
problems. If so then we probably want to restrict this to just MacOS X
and not all platforms in general.
I'd like to push this in before I start the b74 merge (just pushing the
b73 merge now).

FreeBSD 7.x/i386 doesn't exhibit these problems with gcc 4.2.1, so it
seems to be something specific to either MacOS X or Apple's version of
