Re: ls starts VERY SLOWLY w/ b18 on Windows NT 4.0

Wow,
	I figured it out, but it wasn't easy ...
	According to the gnuwin32 b18 readme.txt, b18 adds the intialization of
winsock on startup for all programs.
	My windows nt machine WAS configured to use the microsoft proxy client
when connected to the local lan if the proxy was
available. Since the proxy isn't around, winsock takes a LONG
time (13 seconds or so) to time out. This was happening to me
on all networking programs. I noticed it, but wasn't sure. 
It became unbearable with b18, since even helloworld now took
13 seconds. So, I disabled the ms proxy client winsock and everything
works fine. Wow!
	Thanks for your help!
