With respect to older compilers, it's also worth asking what kind of 
support we should expect - for example gcc-4.4 is a pretty reasonable 
C++03 compiler, but personally I refuse to continue to support C++0x 
mode when that pre-dates the standard and varies from it quite 
considerably.   4.6 and 4.7 also have enough foibles in C++0x mode to 
require a fair number of workarounds, but once we get to 4.8 the 
compiler is good enough not to require too many herculean efforts to 
support.

Just my 2c.... John.
