font-ini needs the following patch
\appendtoks
\dosetmathfamily\mrfam\textface\scriptface\scriptscriptface\c!mr\mrfallback
\dosetmathfamily\mifam\textface\scriptface\scriptscriptface\c!mi\empty
\dosetmathfamily\syfam\textface\scriptface\scriptscriptface\c!sy\empty
\dosetmathfamily\exfam\textface\textface \textface \c!ex\empty
\dosetmathfamily\mafam\textface\scriptface\scriptscriptface\c!ma\empty
\dosetmathfamily\mbfam\textface\scriptface\scriptscriptface\c!mb\empty
\dosetmathfamily\mcfam\textface\scriptface\scriptscriptface\c!mc\empty
\dosetmathfamily\nnfam\textface\scriptface\scriptscriptface\c!nn\empty
\to \mathstrategies
\appendtoks
\dosetskewchar\mifam\defaultskewcharmi % implemented later on
\dosetskewchar\syfam\defaultskewcharsy % implemented later on
\to \mathstrategies
\def\dosetskewchar#1#2%
{\ifx\@@fontskewchar\empty
\skewchar\textfont #1#2%
\skewchar\scriptfont #1#2%
\skewchar\scriptscriptfont#1#2%
\else
\skewchar\textfont #1\@@fontskewchar
\skewchar\scriptfont #1\@@fontskewchar
\skewchar\scriptscriptfont#1\@@fontskewchar
\fi}
i'll patch the distribution
