[OS X TeX] The Babel bug - how it has been introduced.

[Claus Gerhardt]

After installing TL2005 I wanted to check, if the babel bug is still 
present and removed the version of babel.def with Bruno's fix, and 
voilà, everything was fine. Then, I noticed that I was using an old 
modified amsbook class file residing in my personal texmf folder, and 
typesetted a paper using amsart for a change. Sure enough, the bug is 
still there.

The amsbook.cls is from Oct 2000, version 2.08, and apparently some 
later versions of amsart, and probably also of amsbook, are 
incompatible with the babel.def, which, I suppose, haven't changed at 
all with respect to the incompatible definitions and commands. My 
modifications of the amsbook class most likely had no effect with 
regard to the interaction with babel.def, though I modified some 
definitions for the headers too.

Although, the bug can be fixed, one conclusion should be drawn: in case 
of important source files not only a back up of the source but also of 
the tex components, they rely on, should be a standard precautionary 
measure.
