Dear Maintainer,

I am sorry if my bug report is pure ignorance of the matter: I hope
that you would highlight the situation for me at least if it is so

After recent upgrade, mcc (Matlab compiler fails to compile) with next
error messages:

Thank you Bastian! I've adjusted
matlab_r2006b/bin/mbuildopts.sh
on the box to use g++ as the linked and it works now fine ;-) Thank you
very much and once again, sorry for the ignorance ;-)

P.S. I am closing the "bug" since the issue got resolved
P.S.S. Vladimir - just use the most recent r2006b release of Matlab ;-)
