I am using GhostScript 1.3 with the patches supplied by Tony Li and
snoopy's fix to interp.c.  My platform is an 8MB Sun 3/50 running
SunOS 3.5.  I am compiling with GCC 1.35.

As distributed, gs waits for two carriage returns before starting up.
This is annoying, and makes it difficult to redirect input to gs from
a PostScript file.  The cause of this problem is a getchar() in x_open
that bears a mysterious comment saying that ``X LOSES OUTPUT
OTHERWISE.''  Well, I removed the getchar() and haven't lost any
output yet.  Would the person who put in the getchar() please send me
a way to reproduce the problem it went in to fix?  In the meantime, I
intend to run without it.
