Thanks for reporting it. FYI, It's an issue with newlib (the library 
used in Cygwin), not with gcc.

Unfortunately, I don't have a solution for this ... it also happens
on other newlib supported targets, such as powerpc-eabi using newlib

For future reference, please include complete code (eg., without the 
missing <stdio.h> include!), and also when you mention "correct result 
on other platforms", please be explicit as to what that correct result 
is. It may be obvious in this particular case, but you'd be amazed how 
many bug reports are never looked at due to ambiguous or insufficient
