Thanks much for the reply, Daniel. Replies inline ...

Fair enough.I wound up working around this by adding some "#ifndef
HAVE_GSSMIT" around the duplicate definitions in config-win32.h. Seemed
to do the trick.

I know. But unfortunately, that's the version we're currently using
here at work, and we can't really upgrade until our next major release.
  So I'll have to be pinned to that version for now.

Yeah, after some googling, I turned up the WSAEMSGSIZE as well. I
originally just altered the code to change it from EMSGSIZE to
WSAEMSGSIZE, but using a define like you suggested is definitely a
better idea.

Well, I'm testing it out for you now! :-)

Seriously, though, it looks like we're going to need this at my job for
a project we're working on, so there's a good chance I'm going to be
hammering on getting these aspects of curl's functionality working in
the coming weeks (i.e., building on win32, and GSS and SPNEGO support).
  If that does in fact come to pass, I'll be happy to send some bug fix
patches your way to get this stuff cleaned up in the code.

Anyway, re: getting my progress in getting the code built, first some
good news:

I've finally got this all compiling on win32 using HAVE_GSSAPI (and
HAVE_GSSMIT) and HAVE_SPNEGO (against MIT Kerb for Windows, OpenSSL, and
fbopenssl)! (w00t!)

But then some bad news:

I'm now getting some linker errors:

curllib warning LNK4098: defaultlib 'MSVCRT' conflicts with use of other
libs; use /NODEFAULTLIB:library

curllib error LNK2005: _malloc already defined in LIBCMT.lib(malloc.obj)

curllib warning LNK4006: _malloc already defined in
LIBCMT.lib(malloc.obj); second definition ignored

curllib fatal error LNK1169: one or more multiply defined symbols found

Got any suggestions?
