Please, first: i must admit i am standing in no man's land and
found it out only by trial and error.

It seems that the eqn preprocessor does not like that you use .EQ
.. .EN before that ".de $c".  If you move that .EQ .. .EN
downwards then anything is fine.  Except for placement of page
numbers, the fonts i do not know about, and the ".fam" requests
without argument provoke a division by zero error.  Despite all
that it seems to solve the problem.

Oh, surprisingly (eqn is for mathematicians!): using the eqn
"delim" request with dollars seems to start an inline equation for
".de $c"!  You can use the -N eqn command line option to prevent
crossing newline boundaries, but i am, you recognize this?, acting
beyond my current capabilities.  It seems to me eqn(1) should not
interpret data on command lines as inline equations?  No, this
cannot be a solution either, think of equations as part of
chapter names...  No, as inelegant as it is, it seems you must
ensure that the dollar $ delimiter becomes activated after you
have adjusted the me macros.

Staying alive on a saturday night maybe,
Ciao!
