Hi João,
this is pretty cool! 

I would suggest that for completeness there will be 'compile-header' rule that 
works like like 'compile' but only taking header as input (and doing 'cast' 
inside).

Otherwise, I don't see any reason why this should not be added to 
tools/testing.jam

Speaking about header names and escapes, unfortunately I don't see any good 
solution. Header names clashes are possible, and we need to escape slashes 
somehow. Maybe using dashes or underscores would be better, though.

Thanks,
Volodya
