I think, is the lib who can be build with cygwin, but you can use it.

Is other problems in myngw besides socket.h.

I use cygwin to compile sane for windows, libusb have problems because 
is not shared, so a warning that the backend libraries are generated 
static is show.

Also sane-find-scanner have some weird errors, that is because usb.h is 
using the symbol interface, the usb.h from libusb-win32 have some 
defines about that but is not enough, I have to rename in usb.h and 
sane-find-scanner.c to other name, then sane-find-scanner.exe compile 
and work.

For scanimage.exe, the default compile don't work, I set SANE_DEBUG_DLL 
to 4, the program try to load /usr/local/lib/sane/cygsane-epson-1.dll 
(for the epson backend) who do not exits, instead there are 
libsane-epson.a, because I read in the warning that you need to put a 
-dloption I modify the Makefile and put:

LDFLAGS = -dlopen /usr/local/lib/sane/libsane-epson.a

when compile a warning is show, so this is probably the wrong way to 
do, but the program works!.

Anyway, I think some windows developer need to be put in charge and 
clean this distribution and generate a binary for Windows, in other 
words try to imitate Mattias Ellert and the excellent support for 
MacOSX.
