Re: Print to PDF under Windows [changeset-3]

[Tatsuro MATSUOKA]

Hello Ben

Thanks for your efforts.

I have installed two ghostscript. One is for native windows (gswin32.exe ) and 
the other is for cygwin
(gs.exe).

This patch seems to search ghostscript in the order of  'gswin32c.exe', gs.exe 
and gs?
If it is so, is 'gswin32c.exe' selected even for cygwin ?
If it is the case, it will be bad for cygwin.

I think that it is OK to search 'gs.exe' or 'gs' when isunix() is true.

For the people who do not like to use non standard ghostscript binary (e.g. who 
would like to use
gswin32c.exe but not gs.exe from cygwin) , they should set 'GSC' environmental 
variable.


Marco, who is a maintainer of cygwin version maintainer, perhaps have similar 
opinion on this matter. 
Please see his reply for 'OCTAVE_PROG_GHOSTSCRIPT for windows'.

At this post, it is also better to hear Macro's opinion.

Regards

Tatsuro
