Hi Denis,
Thanks for the report. More below...

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.

ISTM the above could be fixed by moving "#include <sys/cpuset.h>" after all the
typedefs in <sys/_pthreadtypes.h>. That would be an odd location for an #include
though. Another approach would be to have explicit external refs for the needed
two functions in <sys/cpuset.h> and remove the #includes there.

I don't have an answer for these. Awaiting more input from our wizards. I'm
willing to submit the patch for any agreed solution.
