Hi Robert,

Fails here with gcc-4.4 and msvc-9.0, too.

It seems that the library names  coded in the test are not those generated by 
Boost.Build. For a quick test I've just inserted the generated names and the 
test start to run.

The gcc test then triggers an assert, but it at least loads the plugin.

The best solution would be to force Boost.Build to always use 
"dll_polymorphic_derived2.dll" as the library name. Otherwise you could 
compose the library name using the autolink-magic.

I've cross-mailed this to the Boost-Build list, in case someone has a better 
idea or even a solution.

Yours,

Jürgen
