[boost] Borland patch for numeric traits test

From: AlisdairM (alisdair.meredith_at_[hidden])
Date: 2006-11-19 04:53:01

This is another patch for a test case, as it is the test case that
exploits the Borland bug.

Essentially, BOOST_STATIC_CONSTANT cannot be used inside a member
template on this compiler, so we need to fall back on using an enum in
those cases.

Updating the test case with this workaround shows that Borland can use
the tested library correctly, so I would like to apply the patch to
both mainline and rc_1_34_0 branch.
