Font change in .28?

[Matthew Persico]

Greetings,

Under Windows, I routinely hand-edit faces.c to change the default
font from Lucida to Courier before rebuilding.

Under UNIX, I found that the default font was Courier and I had to do
no such massaging.

However, with the latest version (.28), I find that the default font
has changed from Courier on the UNIX-compiled version and I cannot,
for the life of me, figure out where that is set in the code.
Moreover, the default font is not a fixed-width font, so I cannot even
really "live with it" until I get it fixed - I am dropping back to .27
for now, which, using the same environment as .28 has the "right"
fonts.

Can I get some guidance here as to:

1) What line of faces.c needs to be twiddled to return the default to Courier?
2) What statement I could put in my local .xemacs config files to
accomplish same?
3) What statement I could put in a global .xemacs config file to
accomplish same? What should be the name of that file and where should
it be placed (xemacs/site-lisp)?

Sorry to be a pest, but the last few releases of xemacs-beta have
required so little tweaking on my part that I am a bit rusty.

TIA
