i was not quite able to work out what exactly happens in your build (i
have also not tried ECL versions newer than 0.9h, which worked), but i
suspect you are maybe ending up including the wrong header file(s).

here is how i usually build the MRS library and include file:

  ECLROOT = /usr/local
  LKBROOT = $$DELPHINHOME/lkb

  [...]

  #
  # rebuild MRS and FSPP libraries, using an installed ECL binary
  #
  mrs:
          ( \
            echo "(load \"$(LKBROOT)/src/general/loadup.lisp\")"; \
            echo "(compile-system \"mrs\" :force t)"; \
          ) | $(ECLROOT)/bin/ecl
          ${RM} -f rmrs.h
          ${LN} -s $(LKBROOT)/include/mrs.h rmrs.h

thus, both `mrs.h' (an ancient part of PET) and `rmrs.h' will be in the
local `cheap' directory, and both should get included, the latter only
in `petecl.c' though.  --- maybe sorting this out will help?

bernd, i believe the original PET MRS code is defunct and could as well
be removed, i.e. `mrs.cpp' and `mrs.h' deleted and call(s) purged.  the
only users of related functionality i know of are the people at CST who
(at least one year ago) were using the mrs_stamp_fs() functionality.

but in case they are still using this, they are probably using the code
in the older `oe' branch anyway, i.e. cleaning up `main' cannot hurt.

                                                          best  -  oe
