I hope this information is enough (else I'm really in trouble to
generate a minimal example).


Greetings,

Here is a minimal example:

beginfig(1);
pickup pencircle rotated 1;
draw unitsquare;
endfig;
end.

And this is a working patch:

(change in supp-pdf.tex)


\def\presetMPconcat
   {\ignoreMPspecials
    \dimen 0=\gMPs1\onepoint   % s_x
    \dimen 2=\gMPs2\onepoint   % r_x
    \dimen 4=\gMPs3\onepoint   % r_y
    \dimen 6=\gMPs4\onepoint   % s_y
    \dimen 8=\gMPs5\onepoint   % t_x
    \dimen10=\gMPs6\onepoint   % t_y
    \keepMPspecials }

Many thanks again. Texexec runs now without any warnings/errors, but the
resulting pdf is corrupt ("Error while parsing a Form, Type 3 font, or a
Pattern.").

I cannot reproduce that. It looks like you need to provide a minimal
example after all. :-(
