can't compile coreutils-9.3 any more after upgrade to cygwin-3.4.8

[Denis Excoffier]

Hello,
When i try to compile coreutils-9.3 under cygwin-3.4.8 i get the following error messages (see below).
There seems to be a kind of loop in the hierarchy of #includes.
Moreover, with cygwin-3.4.7, this is ok. Also, if under cygwin-3.4.8 i remove the 2 #includes from /usr/include/sys/cpuset.h,
this is also ok.

Regards,

Denis Excoffier.
