[boost] [config] Updated Borland compiler config

From: AlisdairM (alisdair.meredith_at_[hidden])
Date: 2006-02-25 08:53:56

This is the second half of my proposed config update for the Borland
2006 compiler.  Main changes are:

i/ pragma to warn users that old compiler support is deprecated in
Boost 1.34.
ii/ Unknown compiler test moved from end of file to start, where it
keeps company with the unsupported compiler tests.

iii/ Library detection macros should simplify workaround detection.
With 3 different vendors to support across different versions, and
library selection further controlled by _USE_OLD_RW_STL macro, we need
something simpler like this for library maintainers to test.

I will be posting further patches using these library macros once this
patch is accepted, and I see a test cycle from metacomm showing no
unexpected problems.
