Building libusb1.0 from source using

$ cygport libusb1.0.cygport download
$ cygport libusb1.0.cygport prep
$ cygport libusb1.0.cygport compile

fails with:

/usr/src/libusb1.0-1.0.21-1.src/libusb1.0-1.0.21-1.x86_64/src/libusb-1.0.21/libusb/io.c:
In function ‘usbi_io_init’:
/usr/src/libusb1.0-1.0.21-1.src/libusb1.0-1.0.21-1.x86_64/src/libusb-1.0.21/libusb/io.c:1167:2:
error: implicit declaration of function ‘close’; did you mean
‘_lclose’? [-Werror=implicit-function-declaration]
  close(ctx->timerfd);
  ^~~~~
  _lclose
cc1: some warnings being treated as errors

I also built with the latest upstream release, but that generates a
great many warnings, which I have not attempted to resolve.

Any guidance to resolve this is appreciated.
