All, I just hit a snag in generating formats with --make --all. It works flawlessly on my computers running Mac OS X or linux, but ALan Bowen has a problem where .pat files with Unicode characters aren't recognized: (/usr/local/teTeX/share/texmf.local/tex/context/patterns/lang-us.hyp) language : patterns agr for agr loaded (n=24,e=agr,m=agr) (/usr/local/teTeX/share/texmf.local/tex/context/patterns/lang-agr.pat !

I compared the cont-en.log of our computers; the only real difference is the beginning: My log: This is pdfTeX, Version 3.141592-1.40.0-beta-20060213 (Web2C 7.5.5) (INITEX) 26 MAY 2006 19:42 entering extended mode \write18 enabled.

So the only difference that really could matter: 1. older version of pdf(e)tex; 2. natural.tcx is not called. Can anybody help? I'm unable to reproduce the problem here; I can generate formats both with texmfstart texexec --make --all and with fmtutil-sys --byfmt cont-en. Best Thomas
