Compiling and linking with MinGW and MSYS (undefined symbols)

Hi,

I'm trying to build a GNU/Linux application on Windows using mingw, 
msys, and gnuwin32.  The application builds with Autoconf.  It has a few 
dependencies that I've been able to sort out by just massaging the 
generated Makefiles a bit, and so I attempted to do the same for the 
relevant gnuwin32 portions.

I have a default install of mingw and msys in C:\mingw and c:\msys, 
respectively.  gnuwin32 is installed in c:\gnuwin32.  I added a line to 
msys' /etc/fstab so that gnuwin32 is mounted at /gnuwin32.  I had 
numerous breakages before adjusting my CFLAGS to include the gnuwin32 
directory, and so I know the compiler is finding them -- in fact it 
compiles cleanly.  I'm not sure, however, that I did it 100% correctly, 
and I'm certain that something is not right with how I attempt to link 
the application:

quake2world_CFLAGS = -pipe -Wall -Werror -I/gnuwin32/include/glibc 
-I/include  -I/sdl/include
quake2world_LDADD = -L/gnuwin32/lib -L/lib -L/sdl/lib -lgw32c -lmingw32 
-lm -lole32 -lwsock32  -lSDLmain -lSDL

And the build output towards completion:

Clearly, it's missing some very basic things.  Is there a dependency for 
gnuwin32 that I'm missing?  Do I need to copy the msvcrt.dll somewhere, 
and link against that?

Thanks in advance,

Jay
