gcc 4 is the new default, specifically the MinGW "setjmp/longjmp" build, 
gcc-sjlj.  If you want to use the old 3.4.5, you need to edit MkRules, 
setting BUILD=GCC3.

For now, the Windows toolset I put together 
(www.murdoch-sutherland.com/Rtools) includes both versions, so you might 
want to download a new copy rather than continuing to use the old one; 
sometime after the release of 2.6.0 I'll drop 3.4.5 from the tools.
