- for PCH gb_CxxObject__set_pchflags should be modified too.

- shouldn't the new flags be initialized in gb_LinkTarget_LinkTarget?

- (as a general rule) for non-obvious commits, please include in the commit 
log message not only what but also why, such as a link to this thread. In a 
year somebody's bound to want to reshuffle the flags and wonder about the 
commit.
