Thank you very much for your contribution. The gcc-3.x compatibility issue
surfaces regularily. Recently Alexandre Tolmos has merged the old patch
prepared by Michael Buro addressing exactly this same problem, and is
currently in the phase of testing it on Compile Farm.

This unfortunately means, that some work has been done twice.
Nevertheless, it would be reasonable to try to merge your changes after
Alexandre is done, so that we are sure that no detail has been lost. If
you feel comfortable with CVS merge facilities I would encourage you to
merge yourself (send me your SF userid for CVS access). This however may
be tedious, so if you do not volunteer to do this part, I can do it.

Next time, I would suggest that you first contact the mailing list or me
directly to discuss the contribution you would like to make. The project
resources are scarce and I would hate to waste time of any contributor.

I am not sure if you are subscribing to the OpenC++ mailing list, since
gcc-3.x patch was discussed here. If not, I would strongly suggest that
you do subscribe (see http://www.csg.is.titech.ac.jp/~chiba/openc++.html
for instructions on how to subscribe). The list is low-volume (typically
0-5 messages a day) and keeps you updated about the project news. It is
archived at

    http://sourceforge.net/mailarchive/forum.php?forum_id=11832

since Sep 2002.

Why don't you join the project? There is quite reasonable testing
environment on Source Forge Compile Farm.

I am deliberately delaying upgrade to new GC, because all currenly
available versions have problems with 'make dist'. I fixed it, Hans Boehm
will include it in 6.2alpha4 ("to be released in the next few days") and
this is probably what we will incorporate soon (also because of MacOS X
port by Alexandre Tolmos).

This is my packaging error. I will fix it when I have a bit of time and
release as 2.6.1 . Thanks for spotting this.

Best regards
Grzegorz
