I think that I have finally managed to come up with the magic numbers. 
The following work fine for LM, times, fourier and palatino. \xmapsto 
also works fine with euler, but harpoons do not work with euler 
(missing symbols).

Hans, can you change the definitions in math-ext to

\definematharrow [xmapsto]            [3599]      [\mapstofill]
\definematharrow [xleftrightharpoons] [3399,3399] [\leftharpoonupfill,\rightharpoondownfill]
\definematharrow [xrightleftharpoons] [3399,3399] [\rightharpoonupfill,\leftharpoondownfill]

None of the extensible arrows work with antykwa-torunska as \relbar is 
not of fixed width in that font. Are there any other free math fonts 
that I should check?
