Changed templates and typeinfo to use linkonce linkage instead of weak linkage, this should fix inlining problems, fixing bug #197 . If problems show up, it's easy to change it back by changing the define in mars.h . I'm 95% sure this is safe, given how we handle templates.

Changed templates and typeinfo to use linkonce linkage instead of weak linkage, this should fix inlining problems, fixing bug #197 . If problems show up, it's easy to change it back by changing the define in mars.h . I'm 95% sure this is safe, given how we handle templates.

Changed templates and typeinfo to use linkonce linkage instead of weak linkage, this should fix inlining problems, fixing bug #197 . If problems show up, it's easy to change it back by changing the define in mars.h . I'm 95% sure this is safe, given how we handle templates.

Changed templates and typeinfo to use linkonce linkage instead of weak linkage, this should fix inlining problems, fixing bug #197 . If problems show up, it's easy to change it back by changing the define in mars.h . I'm 95% sure this is safe, given how we handle templates.

Changed templates and typeinfo to use linkonce linkage instead of weak linkage, this should fix inlining problems, fixing bug #197 . If problems show up, it's easy to change it back by changing the define in mars.h . I'm 95% sure this is safe, given how we handle templates.
