[Boost-build] Options for a compiler version

Subject: [Boost-build] Options for a compiler version

For a given compiler major version number, or for a given compiler major 
version number and minor version number, I would like to:

1) set a compiler option in a test or in an alias
2) not run a test or an alias
3) set a project option

How does one do that with Boost Build ?

For a given compiler major version number on up ( or on down ), or for a 
given compiler major version number and minor version number on up ( or 
on down ), I would like to:

1) set a compiler option in a test or in an alias
2) not run a test or an alias
3) set a project option

A single practical example ( among many ) :

For gcc greater or equal than 4.3 I need to set the -std=c++0x option 
for a test.
