How good is Zortech C(++)?

[house ron]

I recently posted a query in msdos.programmer about the quality of
Zortech C and C++.  My initial query was sparked when I noticed that in
gnuchess, the Zortech version has had all multi-dimensional and huge
arrays removed.  If that was really necessary, there must be something
seriously wrong with Zortech C, surely?  I have only received a few
responses, with the following results:

1.	Zortech macros are defective; it cannot handle nested macro calls:
	   FRED(FRED(x))

2.      It is loaded with bugs.

I am interested in following this up, and compiling a full opinion
report on Zortech C and C++.  Would anyone with any information about
the completeness, usefulness, and correctness of these products please
contact me, and I shall compile a report and post it to these newsgroups.
As the latest version is, I believe, very different from the earlier one,
please state which version you have tested.
