I believe this is because the MM macros use the \g (return register
format) escape sequence, which does not exist in C/A/T troff.  There
are several places in the macros that you'll have to fix.
Sorry, I don't have the fixes around here.  What you need to do
is find all the number registers whose format is referenced
with \g (backslash g).  Then, every place that those number registers
have their format changed with ".af" you will need to remember the
format in a string register that isn't used (.ds xx format, one
string reg per number reg).  Then, you need to replace the \g's
with references to your string registers.
