Aside: it isn't my experience that vsextcomp is necessary to 
cross-compile for AMD64 and IA64. My cross-build process basically 
equates to:

- Run the appropriate environment setup for the correct compiler. E.g., 
for the Platform SDK AMD64 compiler and with the current Platform SDK 
this is:

   C:\Program Files\Microsoft Platform SDK\SetEnv.Cmd /X64 /RETAIL

- Run the solution file with "devenv.com" (IIRC, devenv.exe doesn't take 
command-line args) and be sure to pass ing "/useenv" to pick up the 
environment changes. (*)

   set DEVENV_COM=path/to/devenv.com
   %DEVENV_COM% PCbuild\pcbuild.sln /useenv /build ReleaseAMD64

(*) Note that for a cross-build the "make_versioninfo" and 
"make_buildinfo" projects need to be built natively first:

   "C:\Program Files\Microsoft Visual Studio .NET 2003\Vc7\bin\vcvars32.bat"
   %DEVENV_COM% PCbuild\pcbuild.sln /useenv /build ReleaseAMD64 /project 
   %DEVENV_COM% PCbuild\pcbuild.sln /useenv /build ReleaseAMD64 /project 

This is all VS7.1, though. I don't yet know if VS8 throws a spanner into 
the works. For VS6 I use "msdev" instead of "devenv.com" and 
"PC\VC6\pcbuild.dsw" instead of "PCbuild\pcbuild.sln".

I haven't looked into what vsextcomp does, so apologies if this is ignorant.
