cpython/PC/dllbase_nt.txt

In Win32, DLL's are "pre-linked" using a specified base address.
When the DLL is loaded, an attempt is made to place it at
that address.  If that address is already in use, a new base address
is selected, and the DLL subject to fixups.  Apparently, these
fixups are very slow, and significant performance gains can be
made by selecting a good base address.

This document is to allocate base addresses to core Python
and Python .PYD files, to give a better change of optimal performance.
This base address is passed to the linker using the /BASE
command line switch.

Mark Hammond: * Base address for all extension modules updated. PC\dllbase_nt.txt also updated. Erroneous "libpath" directory removed for all projects. * winsound module moved from a builtin module to an extension module. This was done primarily to avoid Python16.dll needing to pull in winmm.dll. Really dumb test added for winsound - but if nothing else it ensures the module imports. 2000-04-21 21:26:43 +00:00			`- _socket 1e1D0000 - 1e1E0000`

Start building the bz2 module on Windows. CAUTION: The Python test still has many failures, but I'm out of time for this now (already took much longer than hoped to get this far). The base bz2 library does pass its own tests (see next). CAUTION: People building on Windows have to download and build tne bz2 compression libraries now.
