It's an unsettled matter if/whether Cygwin should supply a sys/syscall.h. I cobbled together something to allow the util-linux, and something else maybe FUSE-related, to complete build without angst. The following script creates on stdout something that works. Direct stdout to /usr/include/sys/syscall.h if you dare ;-).
