Bug#409749: ppchtex broken

[Soeren Sonnenburg <bugreports@nn7.de>]

Package: context
Version: 2007.01.23-1
Severity: important
Tags: patch

ppchex will always fail with

===snip===
! Undefined control sequence.
\dosetsubscript #1#2#3->\dimen 0=#3\fontexheight 
                                                 #2\setxvalue {@@\string #1\...
l.158 \stopchemical
===snip===

as fontexheight is undefined in /usr/share/texmf/tex/context/base/ppchtex.tex

To fix this one needs to add the following line to ppchtex.tex
 (to for example line 15)

\input syst-fnt.tex
