Building libusb1.0 from source fails (Attn maintainer)

Windows 10 Home
10.0.17763 Build 17763

$ uname -a
CYGWIN_NT-10.0 mars 3.1.2(0.340/5/3) 2019-12-21 15:25 x86_64 Cygwin

fully patched as of today (no test versions or snapshots installed)


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.
