I reviewed all the compiler options used by db_static.vcproj -- the only thing I needed to bring over was -DDIAGNOSTIC for debug builds. Everything else either had no impact and could be safely dropped, or conflicted with compiler options used by the rest of the python build (function level linking, buffer overflow checks, etc).
Regarding support for users who want to build with different versions of bsddb; if they want a functional build that passes tests they're going to have to do something similar to the work I've done anyway. As it stands now, the .lib generated by db_static.vcproj for x64 builds just straight out does not work. That can be fixed in two ways: coerce db_static.vcproj into matching our build, or mimicking db_static in a new .vcproj that's contained with our build, inheriting our property sheets. I chose the latter.
