Hence it being a workaround to the install issue.

Agreed.

Thanks! Your hint lead to a solution that works for:

   bjam --v2 install msvc-7.1 link=static,shared

The Wave/FileSystem issue is solved by adding 'r' when rtti=on.

The DateTime issue is a more global one relating to building link=static
and link=share at the same time. The msvc compiler produces a LIB
file in both these cases (static produces a STATIC_LIB target and
share produces an IMPORT_LIB target). These targets clash, hence
the error.

The solution I have gone for is to add "-imp" for IMPORT_LIB targets.
Therefore, link=static will produce:

   boost_date_time-***.lib

and link=share will produce:

   boost_date_time-***-imp.lib
   boost_date_time-***.dll

This causes the above install to work. I haven't done extensive
testing, just the above. If this is approved, I will commit it.

NOTE: I don't know about other combinations.
