Perhapse it would be useful to ship updates that will update Boost.Config
and Boost.Build to support the newer compilers.

Boost currently (partially) supports the Borland compiler. If support for
the new compiler isn't there, it would be useful to submit a patch to update
Boost.Config correctly.

I know that the Octonion/Quaternion library failed to compile on older
versions due to a strange preprocessor bug. It has been mentioned that the
new version fixes a lot of preprocessor issues, so can these libraries be
compiled properly now?

I would say that dropping VC6 and GCC2.95 are good choices as these are
already supported in the older versions of Boost, so the issue outlined
above doesn't apply to these compilers.

However, dropping support for the Borland compilers (even though I hasven't
used them for a long while now) is a different matter, because it applies to
the entire compiler chain. I don't agree that Boost should drop all support
for the Borland compilers. For those libraries that do support Borland
compilers, it would make sense to drop support for BCB5 as this is similar
to dropping support for VC6.
