dvips(k) and popen

[Jerome BENOIT]

Hello !

I plan to make teTeX available under cygwin distribution (contrib)
in few days.
Before to upload I woud like to fix the popen misbehaviour 
of dvips(k):
1] if my ~/.dvipsrc has the line `o | gv'  [where gv can read pipes],
   when I type `dvips sample2e.dvi' the dvips output is effectivelly
piped;
2] but if my ~/.dvipsrc has the line `o';
   when I type `dvips sample2e.dvi -o ! gv' I got strange behaviours.

Has anyone get a patch that fix it ?

Thanks in advance,
Jerome BENOIT
