%Here's a little hack, that allow you to get the linenumbers of LaTeX's
%warning messages.

%The output is like:
%
%    LaTeX Warning [l.86]: Citation `diggle' on page 91 undefined.

%where [l.86] refers to line 86 in the current file.
%
%You should put the following in a style file:

%----------------------------------------------------------------------
%  warn.sty
%
% \string: for french context
\def\@warning#1{\typeout{LaTeX Warning [l.\the\inputlineno]\string: #1.}}
% and the new name:
\def\@latex@warning#1{\typeout{LaTeX Warning [l.\the\inputlineno]\string: #1.}}
