Well, now I'm really puzzled. I tested again:
x = 2^31
print( ("%.0f     %d"):format(x,x) )

on 5.2.0-alpha and all the betas (rc1 through rc7).

and I keep getting the same results:

--> 2147483648     -2147483648

Since the issue should have been fixed in 5.2, either I'm doing 
something really silly or my toolchain has something wrong. Could it be 
that msvcrt.dll has some issue that mingw cannot work around?

Is there someone else that gets the same results on WinXP (32bit) with 
(TDM) mingw?

Any hint appreciated.
