Dear Grzegorz,

I am at loss here: I lost track of what we are discussing about. 
Just to clear up some confusion: 

Are you commenting on (1) the issue at hand (problems with
placement-new operator) or (2) on the Gcc patch I committed?

If (1):

I have not checked in any patches related to the garbage collector.  I
just proposed a GC patch for the old garbage collector (which I did
not check in) to you in case you would like to experiment with it.

If (2):

I have checked in my patch to the main trunk of the CVS, as you
advised in another post.

Yes, I did run "make test".  Before I applied my patch, it worked for
Gcc 2.95, but OpenC++ did not even compile for Gcc 3.0 and Gcc
3.2 because of the garbage collector's operator-new issue.
After my patch, the situation remained the same.  I am quite positive
that my changes do not break anything that was not broken before I
committed them.

However, using my experimental GC patch mentioned above, OpenC++
compiles.  The testsuite had to be adopted to ANSI C++ because of
namespace issues and "void main()", and I have committed the
corresponding changes now.  It now seems to work with Gcc 3.0, but
fails with Gcc 3.2, apparently because `occ' cannot parse a number of
STL header files coming with that compiler version.

Please note that `occ' currently assumes that you C++ compiler is
called `g++' (or `CC' on IRIX), and there does not seem to be an
option to change this.  Therefore, if your compiler has a different
name (for example, Gcc 3.2 is called `gcc-3.2' on Debian Linux), you
need to edit the line containing "compilerName" in driver2.cc.


As an aside: I subscribed to <ope...@li...>,
but it looks like commit messages are not reflected to this list.  Is
this intended?

Kind regards,
Michael
