That's nice but my experience in the past has been that no one on the 
clang mailing list responded when the inability to even build clang for 
Windows was made known to them.

Furthermore Boost.Build did not support clang for Windows when I last 
tried it.

So if I try to build and use clang for Windows to whom do I report 
problems about clang ? Furthermore does Boost.Build now have support for 
clang for Windows ?

Clang is a great compiler under Linux. And I am willing to try to get it 
to work under Windows using Boost.Build to test Boost libraries, my own 
and others, under Windows, reporting problems to the appropriate places. 
But not if I am once again met by indifference when problems occur.
