* Bug: In <mbkvhdlg>, cast the hash table index entries from pointer
to unsigned long instead of long to avoid negative numbers when
computing the modulo (shows on Cygwin). This was causing <boog>
to crash.
* Bug: In <ppt>, with bison 2.7, yylval must not be re-declared extern
(didn't show on earlier versions).
* Change: In <ocp>, uses "-std=gnu++0x" instead of "-std=c++0x" to
have both C++11 features *and* POSIX features (namely: strdup).
The problem is that strdup is *not* ANSI, but only POSIX and as
such, not defined when c++0x is active. Will have to change
again in the future as gnu++0x is on the way of deprecation...
