    D.G.>   Stanislav Brabec <utx at k332.feld.cvut.cz> report recently that the \multispan
    D.G.> "plain" macro is broken by a change made in PSTricks 97 for LaTeX 2e
    D.G.> compatibility.

    D.G.>   And in any case looking at this problem, I see that the \psspan macro of the
    D.G.> "psmatrix" environment doesn't work because an undefined \iterate macro is
    D.G.> required.

    D.G.>   Stanislav Brabec sent a correction for the first problem, but this did not
    D.G.> solve the one with \psspan. Here is the patch for pst-node.tex that I finish to
    D.G.> found, but this was not obvious at all. And I'm not completely sure that it has
    D.G.> not some side effects.

    D.G.> % DG/SR modification begin - Nov. 27, 1998 - Patch 8
    D.G.> % Workaround for problem with \psspan in LaTeX 2e
    D.G.> %\let\mscount\@multicnt
    D.G.> \newcount\mscount % Only defined in 209 compatiblity mode in LaTeX 2e
    D.G.> \def\psspan#1{\global\mscount#1\loop\ifnum\mscount>\@ne\sp at n\repeat}
    D.G.> \def\sp at n{\span\omit\global\advance\mscount\m at ne}
    D.G.> \def\loop#1\repeat{\gdef\iterate{#1\relax\expandafter\iterate\fi}%
    D.G.> \iterate\let\iterate\relax}
    D.G.> % DG/SR modification end

  My guess was good: since this time, I found that this patch has major
pitfalls and break some usual LaTeX environments.

  So, remove it from your pst-node.tex file if ever you integrated it and
never use this wrong correction. You must wait that I -or somebody else-
found a better solution to the \psspan problem.

  Sorry for inconvenience, if ever. But in any case this patch was not sent
outside the list and not integrated in CTAN distribution, as I always prefer
to test changes in real situation for a certain time before to officially
release them...

D.G.
