When I try to build NIHCL under ATT cfront 2.0 on a SpacrStation
running SunOS 4.1, there are a number of problems.

(1) Many of the 'make' options don't get passed into subordinate
    Makefiles.  This was easy to fix by editing the various Makefiles,
    and I enclose context diffs.

(2) When I try to make the multiple-inheritance version (`make mi'),
    the compilation fails with the following:

"ArrayOb.c", line 72: error: ambiguous Object::nil and Object::nil (one not in v
irtual base)
"ArrayOb.c", line 129: error: ambiguous Object::nil and Object::nil (one not in
virtual base)
"ArrayOb.c", line 140: error: ambiguous Object::nil and Object::nil (one not in
virtual base)
"ArrayOb.c", line 177: error: two initializers for Collection
"ArrayOb.c", line 177: error: two initializers for Object
"ArrayOb.c", line 218: error: two initializers for Collection
"ArrayOb.c", line 218: error: two initializers for Object

Anyone else seen this problem before?  Any suggestions what to do
about it?

Thanks,
