This was 11 years ago, and the bug report unfortunately didn't get a lot
of attention at the time.  However, I think the underlying problem was
fixed by João a few years back, so I'm closing this bug report.  If the
problem still persists in newer versions of Emacs, please respond to the
debbugs address and we'll reopen.

    Completely rewrite Flymake's subprocess output processing
    
    Instead of parsing and matching regexps line-by-line, insert
    subprocess output in a separate buffer and parse using
    `search-forward-regexp'.  This eventually enables multi-line error
    patterns and simplifies code all around.  Store per-check information
    in the subprocess using `process-get' and `process-put'.  Treat error
    messages, warnings, etc. more generically as "diagnostics".  Create
    these objects as soon as possible, reusing existing `flymake-ler'
    structure.  Fix some whitespace.
