I have been trying to use PSGML 1.1.1 (for the XML support) and Emacs
20.2.96 on Windows 95.

The previous combination of Emacs 19.34.6 and PSGML 1.1.1 worked fine,
there also appears to be no problem under Emacs 20.2.1, but under
Emacs 20.2.96, it can't seem to find the catalog file specified in
autoexec.bat:  
set SGML_CATALOG_FILES=.\catalog;c:\dtds\catalog

e.g. When I load an SGML file I have, with this on the first line:
<!DOCTYPE TEI.2 PUBLIC "-//TEI//DTD TEI Lite 1.0//EN">

I get the error message:

"External entity TEI.2 not found
  Public identifier -//TEI//DTD TEI Lite 1.0//EN"

Despite the fact that I have this entry in my catalog file (and the
dtd does exist where its suppossed to):

PUBLIC "-//TEI//DTD TEI Lite 1.0//EN"
       "c:/dtds/teilite.dtd"

I do not know the cause of the problem (bugs in Emacs 20.2.96?), but
suggest you do not upgrade beyond 20.2.1 on Win32 systems until a
solution is found...(reverting back to 20.2.1. 'cured' Emacs'
forgetfulness about the catalog file...)
