[PATCH] Cygwin accomodations for newer gccs

[Christopher Faylor <cgf at redhat dot com>]

Newer versions of gcc for Cygwin no longer implicitly define WIN32
conditionals.

This patch fixes that problem.

Wed Apr  4 21:48:42 2001  Christopher Faylor <cgf@cygnus.com>

	* main.c: Remove windows.h use.
	(gdbtk_test): Use PATH_MAX for home var calculation.
	* remote-e7000.c (e7000_parse_device): Accomodate CYGWIN as well as 
	WIN32 in colon test.
	* ser-tcp.c: Use modern __CYGWIN__ conditional.
	* source.c (mod_path): Add __CYGWIN__ conditional to WIN32 test.
	(openp): Ditto.
	* symfile.c (symfile_bfd_open): Ditto.
	* gdbtk/generic/gdbtk.c: Ditto.
