For those who want it, here are the patches necessary to get the new
ghostview to compile under linux, with shared libs. They're trivial,
but the one in ps.c is interesting - I had to rename a function
because it clashed with a macro defined in ctype.h. This function is
new, ghostview 1.3 didn't need this change.

These are made for my system, and so include a -m486 in the Makefile,
take that out if you don't want it.

These are really just to save you some editing, or for those who like
things to `just work'. I'll mention to the author about the name clash
in ps.c - I have to send him some mail about getting it to run
properly on another platform anyway.

Ghostscript 2.5.2 compiles `out of the box' with no work at all.
