David:

The package I got from CVS on Mar. 14 builds without errors, but I can't seem 
to get it to print. The section below seems to indicate that it is working in 
some fashon.

[root@tumbleweed joe]# /usr/local/sbin/ptal-mlcd par:0 -base 0x378
[root@tumbleweed joe]# /usr/local/sbin/ptal-printd mlc:par:0 -like /dev/lp0

[root@tumbleweed joe]# pidof ptal-printd ptal-mlcd
1124 1122

[root@tumbleweed joe]# ptal-devid mlc:par:0
MFG:Hewlett-Packard;MDL:OfficeJet Series 
600;CMD:MLC,PCL,PML;CLASS:PRINTER;REV:4.03b;


I may just be overlooking something, but with the earlier build problem due 
to compiler differences, this may have a similar cause.

Has anyone yet been able to use gcc-2.95.2 sucessfully with the new code in 
CVS?

Here are some of the messages that appeared on the command line at one point. 
I'm not sure what I was doing when they appeared (possibly trying to print), 
but maybe they'll mean something to you. Sorry if it doesn't help.

The install/print-howto instructions do seem like they could be simplified.
