In a nutshell, the problems with the old implementation of listerrors that
bug 190 refers to were::

\begin_layout Enumerate

It was a C program and it was installed in the user path in the same directory
as LyX.
Having such a generically named binary in, for example,

It required that noweb be installed on the compiling machine (the source

The new version deals with these problems in the following fashion:

the LyX CVS repository.

Filtering errors

The only complication in our filtering code is that some parsers might need
to push back lines that are read in to be read again later.
We solve this problem by implementing a
set of functions:
