I am not trying to get Boost to not support BCB, since I have used it
significantly in the past and am using its prior release, BCB6,
currently on a project on which I am working but...

1) I submitted a number of compiler bug reports in Borland's bug
tracking system circa late 2002, and one even in 2000, many of which
were taken from Boost's reports and verified by myself. I provided test
code to show the bugs in the compiler.

2) Very few of these have been fixed in the latest release of their
compiler, while a great many still remain, are supposedly still open and
being "investigated" still over 3 years later.

This shows to me, unfortunately, that Borland is still not serious about
fixing compiler bugs despite all of the promotion over the latest
release of their product, in which they have upgraded the user interface
to the IDE significantly from all reports. I even mentioned on their NGs
that one of the reasons that fixing these bugs is so important is that
many of the Boost developers no longer want to support the compiler in
their implementations, via workarounds, if Borland is not willing to fix
their bugs. Admittedly Borland employees themselves rarely respond on
their NGs, but the responses to their not fixing these bugs after so
many years appeared to be a big yawn from other developers and TeamB
supporters on those same NGs. So while I have always been a supporter of
Borland in the past I do not see that they are serious about fixing
their compiler bugs, or even consider it important to do so.
