   After our last discussion, I posted a revised patch here:

      http://sources.redhat.com/ml/gdb-patches/2005-04/msg00054.html

   I believe that version reflects the improvements you requested.

   Have you had a chance to look at it?

Oops.  Missed it again.  I looked at it now.

   It's possible to "#define ioctl ioctlsocket" so that ioctl doesn't
   need to change. However, I think it would be very confusing to do
   "#define close closesocket" because there's already a Windows
   runtime library function called "close" -- it just doesn't work on
   sockets. So, in the version of the patch that's attached, we still
   do have a call to closesocket.

But the code only uses close for sockets isn't it?  The point I'm
trying to make is that most people changing this file will be
familliar with POSIX but not with the stupid Windows API.  I really
want this file to look as much as POSIX as possible.  Given that this
file is all about sockets, I think the #define close closesocket might
actually prevent people who are not familliar with windows from using
close() where they should use closesocket().  So I'd still like you to
change this.

Can you remove the extra blank line here?

+       if (status != SERIAL_TIMEOUT)
+ 	{
+ 	  break;
+ 	}

and here (and get rid of the redundant braces.

+       /* If we have exhausted the original timeout, then generate
+          a SERIAL_TIMEOUT, and pass it out of the loop. */
+ 
+       else if (timeout == 0)
+ 	{
+ 	  status = SERIAL_TIMEOUT;

and get rid of that blank line too.

+   if (status <= 0)
+     {
+       if (status == 0)
+ 	return SERIAL_TIMEOUT;	/* 0 chars means timeout [may need to
+ 				   distinguish between EOF & timeouts
+ 				   someday] */
+       else
+ 	return SERIAL_ERROR;	/* Got an error from read */
+     }

Please give these long comments their own line, and make them full
sentences (full stop and two spaces at the end, you know the drill).

With those changes, please go ahead and check this in.
