- garbage was being output sometimes instead of source lines when compiling with -al. This is because lastfileinfo and lastinfile were never initialized for MASM writer. This is true for TPPCMPWAssembler, too.

- long lines were not wrapped.
- constants of type ait_comp_64bit output incorrectly.
- at end of file, current segment was not closed.
patch from Sergei Gorelkin
