Hi!

[Since I don't know if Mr. Korn is reading the gnu-win32 list, I've CC'ed
him and included the whole message at end.]

Sigh, that it's not available...

I wanted to report a problem printing it (there are some typos, too).
Our duplex printer chokes on the embedded figure 1, where setcmykcolor
is called, which is Level 2 PostScript, and that despite some checks!
Ghostscript/ghostview and some other printer handle it fine.
It is used only for a 3D effect on a rectangle, which as well could
have been rgbcolor or grayscale or just black&white, IMHO.
I guess the slides in talk.ps have the same problem (didn't print them).
At least it allows A4 paper, not the usual trouble with letter docs
from Framemaker!

I figured out a fix, if someone cares about:
(Dunno how the fix looks or works on a real color printer...)

: David G. Korn of AT&T Labs (author of the Korn shell (ksh)) presented
: a paper entitled "Porting UNIX to NT" at last week's Usenix conference
: in California.  In it he describes his group's efforts "to build a
: UNIX interface layer on top of the Windows NT and Windows 95 operating
: systems."  The paper does an excellent job of distilling out and
: describing the key issues and problems of this task.  It also
: describes, in some technical detail, their approaches and solutions.
: 
: A PostScript copy of the paper is available at:
: 
:   http://www.research.att.com/sw/tools/uwin/winnt.ps
: 
: I would strongly recommend it for reading to anyone with an interest
: in implementations of UNIX environments/utilities on NT.  I also think
: it might hold some particularly good insights for anyone involved in
: development on the gnu-win32 project.
: 
: The parent page to the URL given above gives an overview to the
: package, called UWIN, created as a result of their efforts.  The
: project, which appears to be even more ambitious than the gnu-win32
: effort, is apparently quite far along.  Unfortunately, it is not clear
: whether the UWIN package will ever become publicly available.
: 
: Hopefully, AT&T Research will see benefits to providing a freely
: available Unix environment for the Windows 95 & NT platforms.  For
: one, it could help break the strangle hold of the cumbersome Win32 API
: and provide opportunities for vendors (such as AT&T) of products based
: on more openly supported programming interfaces.  With any luck, the
: continued success and popularity of the Cygnus gnu-win32 effort will
: help drive this point home.
