I was getting this error on linking an application that uses STL:
unresolved external symbol "const type_info::`vftable'" ( _7type_info@@6B@)
I installed the Emulator\ccrtrtti.lib from the patch provided below into my emulator directory
http://support.microsoft.com/default.aspx scid=kb;en-us;830482
This resolved the issue for the emulator.
I need to do the same for a x86 target. Only issue is that the ccrtrtti.lib is not available for the x86 target in the above patch. Anyone know how to resolve this issue.

EVC4 unresolved vftable error: resolution for x86 target
