Well for example I see:

    "cl"  /Zm800 -nologo -GX -c   /Z7 /Od /Ob0 /GX /GR /MDd /Op
/Zc:wchar_t,for Scope  -I"..\..\bin\boost\libs\regex\build"  -I"C:\Program
Files\Microsoft Visual Studio .NET
03\VC7\include"   -Fo"..\..\bin\boost\libs\regex\build\libboost_regex.lib\vc
7.1\debug\threading-multi\regex.obj"  -Tp"c:\data\boost\develop\boost\libs\r
egex\build\../src/regex.cpp"

Notice for example that $(BOOST_ROOT) is not in the include path (actually
none of the options applied via the template are getting applied, it should
look like this:

    "cl"
 /Zm800 -nologo -GX -c  -DBOOST_REGEX_CONFIG_INFO=1 -DBOOST_REGEX_NO_LIB=1
/Z7 /Od /Ob0 /GX /GR /MDd /Op  /Zc:wchar_t,forScope  -I"..\..\..\bin\boost\
libs\regex\build"  -I"c:\data\boost\develop\boost" -I"C:\Program
Files\Microsoft Visual Studio .NET
03\VC7\include"   -Fo"..\..\..\bin\boost\libs\regex\build\libboost_regex.lib
\vc7.1\debug\c_regex_traits.obj"  -Tp"..\..\..\libs\regex\build\../src/c_reg
ex_traits.cpp"

No joy, it's not that change that broke things.

I tried rolling back further, but that only produced errors within the Jam
system.
