Yes.

I have VS 8 and VC++ Toolkit installed. When I compile using VC++ 
Toolkit and PSDK, neither %DevEnvDir% nor %MSVCDir% present. 
vcvars32.bat from VC++ Toolkit does not set any of them. As result 
SetEnv.cmd runs PSDK\Setup\VCDetect.exe which detects VS 8 installation 
and calls vcvars32.bat from it.

So what I get is:

VC++ Toolkit\vcvars32.bat
VS 8\vcvars32.bat
PSDK\setenv.cmd
cl ...

Actually combining your explanation and mine a solution (for VC++ 
Toolkit configuration) can be found. We can set %DevEnvDir% and 
%MSVCDir% before calling SetEnv.cmd.

The second problem will happen with other than msvc.jam toolsets. If 
neither %DevEnvDir% nor %MSVCDir% is present, SetEnv.cmd calls 
VCDetect.exe. If no VS installations detected SetEnv.cmd won't set 
INCLUDE, LIB and PATH. It will simply print current settings. See below:
