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
1.9.0.
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
information.
Regards,
Mumit
