[Ipopt] compilation of 3.7.0 failed

Thanks!
I added a patch that does this to ThirdParty/Metis/trunk.
Dieter, can you try if that solves it for you?
You can either try to build Ipopt/trunk which you get by
svn checkout https://projects.coin-or.org/svn/Ipopt/trunk

Or you can take a checkout of some release, go to ThirdParty/Metis,
and do a
svn switch
https://projects.coin-or.org/svn/BuildTools/ThirdParty/Metis/trunk
(in one line) there.
If you then do ./get.Metis it should apply a patch after downloading
which renames __log2 to __log2_metis.
