msvc-8.0-e won't work in bjam because it interprets the 'e' as a sub-feature of
the toolset (e.g. msvc-7.1-intel). msvc-8.0e is not clear as to what the 'e'
stands for (energy? experience? ...)

VC8 Express (and VC7.1 Toolkit) place where they are installed to in a
different location to the Standard, Pro and Team System versions. Therefore,
they need to look in different places in te registry. However, I don't see why:
using msvc : 8.0 ;
would not try the standard VC8 install first and if that fails, try the
express version (same for 7.1toolkit). This would simplify the list of
supported versions, however you might wan't both standard and express/toolkit
versions installed on the same machine and invoke each.

There is already logic to detect and configure for x86, x86-amd64 and x86-ia64
variants of VC8. These can be selected using the <architecture>,
<instruction-set> and <address-model> features.
