Yes, I like to reuse the vsprops files. They are useful to share common
configuration and macros across multiple projects in a solution. It
should make it easier to share global information like include
directories. I'm not going to add PGO (profile guided optimization) for
now. It's a nice to have feature but it's not crucial.
A project can inherit from multiple vcprops and a vcprop sheet can
inherit from another. I've given some though to a sensible but small
structure:
pyproject (base vcprops for all projects in the solution, machine
indepdentend)
* pyd (props for Python extensions)
o pyd_d (props for Python extensions Debug build)
amd64 (AMD64 related options)
x86 (x86 related options)

I've planed to work on py3k and port the PCbuild9 stuff back into the
trunk later. The structure of py3k and trunk are almost identical but
the py3k branch has more files. It's easier to remove non existing files
than to add missing files.

What combinations of configuration and platform do we need? The migrated
solution has Release, Debug, ReleaseAMD64 and ReleaseItanium as
configurations and Win32 as platform. The platform X64 isn't listed but
I could add it.
Do we need a ReleaseAMD64 when we could use the platform X64?

I vaguely remember an issue with openssl that is fixed in new versions
of openssl. For now I try to stick to the releases which are already in
the external repository.
I'm not familiar with all settings of VS. While I can make sense of most
settings I don't understand why some projects are setting a base address
in the linker settings.
