Hi,

	After a great struggle (and lots of googling around) i finally compiled cygwin1.dll on
	linux and tested in a win32 environment, the process wasn't straightforward but it worked.

	I've attached the original email body (for long lines format protection) and all changes i've made
	(all trivial) as unified diff.

	What i want, is to know if i have done something *very* wrong in the cygwin configuration
	and compilation, because the cygwin compilation raised a lot of undefined references from
	cygserver, i had to compile cygserver separately and manually (outside autotools) for the
	process to complete, below are the procedures i've followed.
	
	If this listing isn't the proper place to discuss this, please forgive-me and point me the right
	direction.

	I also thank you all for the great work on cygwin.

procedures:
