../lib/libgnu.a(pipe2.o): In function `rpl_pipe2':
/c/src/emacs/64testt/lib/pipe2.c:144: undefined reference to `setmode'
I think the issue here is that pipe2.c shouldn't be compiled on Cygwin.

Paul just submitted a patch to Gnulib that should fix it in a better way than
what I suggested.
One problem was that I tried too hard to not use Gnulib
in Emacs, so I mistakenly avoided Gnulib's binary-io module.
There appears to be another issue, though -- a porting bug in Gnulib when
using the accept4 or pipe2 modules on Cygwin. As Ken notes I
have tried to fix that problem in Gnulib, and propagated the
fix to Emacs while I was fixing the binary-io issue.
Please try trunk bzr 113348 to see whether these two changes
solve the problem.
Yes, that fixes it. Thanks.
For the record, the problem I reported was due to the fact that Cygwin
defines setmode as a macro that expands to _setmode. (So I was wrong
when I said that setmode shouldn't be used on Cygwin.) But this
definition is in <io.h>, which wasn't being #included. The problem
showed up only in the 64-bit build because underscores are automatically
prepended in the 32-bit build.
I'm closing the bug.
