A wild guess would be that he has his set of distributions which ship
with a particular Boost and GCC version.

A solution could be a standalone hackfix that could be propagated
upstream to his distribution, or some evidence that can be used to
motivate installing a slightly higher Boost if it shows that it indeed
solves the problem.

I'd reckon that the question appears out of a belief that it's possible
to make point releases for older versions.

A common policy in some projects is that bugfixes for older supported
versions can be made as point releases, but new features requires a new
full release.

Boost, sadly, does no such thing. At best you get a point-release
inbetween the real releases, but once Boost revs the minor version, all
the old releases are forever set in stone.
