Re: [Partysip-dev] loggin problem in win32

[Zihong Lu]

Finally get some time to test it out.  All I changed
was using "debug multithreaded DLL" for C/C++ code
generation, for osipfsm.dll, osipparser.dll, and all
the projects in partysip, I kept the default libraries
in the link settings without change.  And it worked
now.  

Still don't know why using "debug multithreaded" for
osipfsm.dll, osipparser.dll, and all the projects in
partysip did not work.  Vaguely remember I had
encountered similar situation in VC5 before.

This list is the default VC++ loaded libraries:
Multithreaded           /MT  libcmt.lib
Multithreaded DLL       /MD  msvcrt.lib  (msvcrt.dll)
Debug Multithreaded     /MTd libcmtd.lib
Debug Multithreaded DLL /MDd msvcrtd.lib (msvcrt.dll)


No change to the underscored function calls is
necessary.  The reason I prefer the no underscore
function calls is that the ones without the underscore
are ANSI C compatible, please see
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vccore98/html/_crt_compatibility.asp
for detail.
