Summary: Windows _bsddb link warnings

Initial Comment:
Hi,

The PCbuild/readme.txt says this:

'''
    XXX We're actually linking against
Release_static\libdb41s.lib.
    XXX This yields the following warnings:
"""
Compiling...
_bsddb.c
Linking...
   Creating library ./_bsddb.lib and object ./_bsddb.exp
LINK : warning LNK4049: locally defined symbol
"_malloc" imported
LINK : warning LNK4049: locally defined symbol "_free"
imported
LINK : warning LNK4049: locally defined symbol
"_fclose" imported
LINK : warning LNK4049: locally defined symbol "_fopen"
imported
_bsddb.pyd - 0 error(s), 4 warning(s)
"""
    XXX This isn't encouraging, but I don't know what
to do about it.
'''

The cause of this is the fact that libdb41s.lib is
built with the flags for using the "Multithreaded" C
RTL but Python uses the "MUltithreaded DLL" C RTL.  In
other words, libdb is specifying that the C RTL should
be linked statically but Python wants to link to it
statically. 

To avoid these warnings the instructions can be changed
to specify that the builder should change the flags in
the Berkeley_DB project.  Also you should probably link
with the Debug_static\libdb41sd.lib when building the
debug version of Python.
