Looks like a Cygwin bug (ARG_MAX is supposed to be defined by
inclusion of <limits.h>); it should be reported to the Cygwin
maintainers.

I've been responsible for most of the recent changes to XDRIVER. 
However, I don't have a Windows box, so I can't perform tests with
Cygwin. However, if you can provide me with information as to what's
happening within the programs, I might be able to suggest changes.

For reference, the files which are most likely to be relevant are:

	src/display/devices/lib/main.c
	src/display/devices/lib/connect_sock.c
	src/libes/raster/io.c
