In a nutshell, the problems with the old implementation of listerrors that
bug 190 refers to were::
\end_layout
\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
was extracted by noweb from

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

Both the example file (this document) and the program are to be added to
the LyX CVS repository.
