BetterC + Windows + setjmp longjmp

[SrMordred]

Ok, after a better look at the sources I finally got it:

setjmp is a macro.
the true function signature is "int _setjmp(jmp_buf, void*)"

the void* is the current function address which in mingw sources 
are capture by "__builtin_frame_address(0)".

And I did´t look yet to see if Dlang have an equivalent.
but calling _setjmp(jmp_buf, null); the simple examples are 
working :)
