nesting the macro doesn't fix the problem, but this works:
(the first three .db's are combined into one line)

#define NUM(s,n,e)  .db (n > $FFFFFF) + (n > $FFFF) + (n > $FF) + 3, (e
<< 1) + (s & 1), n & $FF
#defcont            \#if (n > $FF)
#defcont            \.db (n & $FF00) >> 8
#defcont            \#if (n > $FFFF)
#defcont            \.db (n & $FF0000) >> 16
#defcont            \#if (n > $FFFFFF)
#defcont            \.db n >> 24
#defcont            \#endif\#endif\#endif
