Not sure, but I did confirm this "bug" (and with 4.6.2 also).

I recently discovered that GCC 4.6.x versions have some weird
differences. For instance, I'm not sure (and heavily doubt) they were
compiled with "stock" DJGPP, at least verified in /beta/ versions
(which I normally prefer for silly reasons). Could it be a bug in CVS
versions or something clashing in mixing? Dunno ....
