Actually, I just fixed this in CVS last week:

http://sourceware.org/ml/newlib/2013/msg00521.html
http://sourceware.org/ml/newlib-cvs/2013-q3/msg00005.html

This will be in Cygwin 1.7.21 when released; in the meantime, it is safe 
to apply that patch to your existing /usr/include/sys/types.h.

BTW, following up on the previous discussion wrt cross-compiling the 
Linux kernel, my stdint patch is now in the kbuild and linux-next trees 
as commit b35310627f396efcc25d71fb343b3aa02039d20d; hopefully it will 
get into 3.11, but it is also necessary for (and applies clean to) all 
stable branches since 3.3.

HTH,


Yaakov
