[boost] request to patch libs/serialization/build/Jamfile.v2 for support of msvc-6.5

From: Roland Schwarz (roland.schwarz_at_[hidden])

I tried to port parts of the libs/serialization/build/serialization.jam 
to bbv2 for better support of the msvc-6.5 compiler.

I am currently running a regression which seems to have far lower 
failing tests.

To build with this compiler it is necessary to check out the
SPIRIT_RC_1_6_2 branch to a directory first.

In the environmet or better in site-config the statement

path-constant SPIRIT_RC_1_6_2 : "H:/Projects/boost/SPIRIT_RC_1_6_2" ;

has to be added. Of course the shown path needs to be replaced with your 
checkout path. (Forgetting to do this will emit an error message with 
instructions.)

Unfortunately this approach does not help with borland-8.5.2 because it 
still does not compile with SPIRIT_RC_1_6_2 in place. Any help on this 
highly appreciated!

(patch attached)
Roland
