While it should be possible to build a library that will not emit the 
autolink pragmas it is not recommended to do so.

However the dumpbin you are showing indeed is strange.
The upcoming 1.34 version (from cvs) does not show this dependency, it 
correctly shows the LIBCMT in its requirements.

As I do not currently have a 1.33 build around I cannot tell for sure if 
this was a bug in 1.33 or if you made a mistake during the build of the 
library. I will try to verify this.
