Cool. Some bad news for you:

- Recently I submitted my own bugfix-only patch (now including CVS diff)
which fixes some bugs in the toolset. So we should spend some time
merging our patches into one big one. Or to wait until first patch is
reviewed and incorporated, and then change the next patch properly. I
don't know which way is better.

- new feature names and values will need to be carefully selected and
pass a review in order to get accepted. See my discussion about
precompiled headers

We are still looking for contributors who can review other compilers and
propose reasonable rationale for feature names and values for
precompiled headers.

For archiectures etc we need people who can research other compilers.
For example, gcc should have switches for different CPU architectures
already for a long period of time (e.g. MIPS/ARM etc).

SDK is too generic. toolset-mspsdk would be better.

I think we should reverse engineer the PSDK setvar.cmd switches and
check. I think that "platform" switch just #defines WINVER or something
like this. So built-in compiler should support it too.

Only for now. We should remember that later this feature will work for
other toolsets too.

msvc-config is deprecated, isn't it? I think the autodetection should be
built into main MSVC toolset. Or we should have -config pseudo-toolsets
for other compilers too.

I can test:
- MSVC 7.1. with and without PSDK
- MSVC 8.0 (Team System June CTP) without PSDK (beta itself is newer
than any available external PSDK so there's no practical use for VS8.0
Standard edition and higher with external PSDK yet)

We'll also will need a support for VC 8.0 built-in 64-bit compilers. I'm
ready to contribute when all current pending patches will be integrated
or at least reviewed.
