Volodya thanks for all the work on this. The new toolset command line
structure is much better.

Like Christopher I particularly like the change so I can run compilers with
prefixes. "distcc" for example.
So I am glad the gcc toolset does not need to call "get-invocation-command"
and warn. One possibility in this regard would be to allow
"user-provided-command" to contain two elements. The first element could be
the prefix, and the second the actual command. Only the latter would be use
to fine the tool path.

This would provide a general prefixing solution without having to add
additional init parameters.

I have also been thinking about the meaning of the init 'version' parameters.
This particularly interest me as I do things like
using intel : 8.0 ;
using intel : myspecialtest : "special compiler" : "special options";

For this purpose 'version' is simply a user defined freeform tag. It can be
used to specify build targets and matched in optional properties for specific
build requirements.

The exception to this freeform rule is the 'msvc' toolset. Here the 'version'
parameter has meaning and is used to automagically choose paths and options.
I not sure of a good solution to this dichotomy !
