I did run VCVARS32 before, as stated in the documentation. There must
be something else going on.

>From a clean checkout, after invoking VCVARS32.bat, the following works:

.\bjam -sTOOLS="msvc" -sMSVC_ROOT=%MSVCDIR%

If I leave out the MSVC_ROOT variable, it fails. Is there any debug
flag I can set to help in debugging this?

No need. I understand what the problem is, though I'm not sure why it is
that way: the toolset checks for "MSVCDir" because that's what my
VCVARS32.BAT sets, but your VCVARS32.BAT is setting "MSVCDIR". I've fixed
the toolset so it looks for either one. For the next boost release we
probably ought to set up a built-in global variable called ENVIRONMENT or
something which contains the names of all environment variables as they are
set.
