running CPP tests - 2 functions failed

[hcfang2000]

build_mapnik.bat 1> build.log
mapnik.dll seems to be built successfully. But failed the CPP tests.

These 2 tests failed:
exceptions_test.exe - Entry Point Not Found
fontset_runtime_test.exe - Entry Point Not Found

When running c++\rundemo, got the error from a popup panel
rundemo.exe - Entry Point Not Found
The procedure entry point ?add_expressions@text_placements@mapnik@@UAEXAAV?...
... could not be located in the dynamic link library mapnik.dll

How to solve it? Thanks.
