[I posted a bug report due to a conflict between plain tex and
supp-pdf.tex ]

Thanks Hans, that fixed the \outer problem with \newdimen.
I noticed in the comments for the patch a sigh. I'm too ignorant to
know whether you being constrained by maintaining compatibility with
plain TeX has degraded supp-pdf.tex.
I also posted a report to comp.text.tex, where Dan Luecking (author of
\mfpic), patched the \outer macro \newdimen by replacing it with
\csname newdimen\endcsname
on the two offending lines. If it's helpful, Dan Luecking's patch
does work inside the \beginETEX ... \endETEX definition.
