[boost] Boost_1_28_0 - RegEx build with debug symbols produces incorrect files.

I've been working on getting the latest version of Boost built
(MS VC6 SP5) and have noticed some problems.

The debug builds (or release build if '<debug-symbols>on' is set) 
produce (correctly) a PDB file for the dll.
The problem is, the filename of the DLL and PDB are always created as 
boost_regex.[dll/pdb].  Well, with a debug build, the dll is copied
to boost_regex_debug.dll (as well as the import library).  Well, the
end result is good, in that the debug-build has a different name, but...

With VC, DLL's/PDB's contains embedded information based on how they 
were created (such as the name of the matching pdb/dll).  Unfortunately, 
in this case, these names will no longer be the same.  As a result, VC 
will always try to load boost_regex.pdb, not boost_regex_debug.pdb.
That's probably fine, as long as you don't need to debug a 'release' 
buildp problem.  Basically, the PDB's that are created (debug & release) 
have the same name, and reference the same dll name (boost_regex.dll) 
regardless of how they were compiled.

The configuration needs changed to actually explicitly create 
boost_regex_debug.dll, boost_regex_debug.pdb, boost_regex_debug.lib at 
compile/link time, not as a result of a post 'file copy/rename' operation.

As it stands, I don't see how it would be possible to debug both release 
or debug builds of the boost regex dll.

Comments?  Am I way off base here?

Thanks,
