Didn't we decide to drop ancient compilers?
Not yet, but we never officially defined what it means to support a compiler either.
There is certainly a growing feeling their time has come, but no definitive list yet.
Microsoft have dropped all support for VC6 for some time now. Several Boost libraries (such as Spirit) have dropped support for this compiler.
I have proposed deprecating MSVC6 and GCC2.95.3 in this release (1.34) so that users at least get some notice they are vanishing. I would then hope the compiler config would still detect these compilers, and #error with a message saying Boost 1.34 was the last supported version, so anyone trying to use them at least knows which old version of Boost to retrieve (and likewise, I recommend this for any formal deprecation policy we finally adopt)
It may be useful if Boost.Config still detects the functionality for the compiler(s), so you could use it with, say, VC6 in your own project. A message would be better than an #error as you could still use components that still work with the older compilers. - Reece
