Wine automatically adds the -m32 flag to gcc to force it to compile in 
i386 mode.

That's fine.

As is this.

I think this is the problem. Is this a default symlink on your distro or 
was it put there by installing kernel source?

In 32-bit mode the i386 headers should be used instead of x86-64 ones. 
On your system this isn't happening, although the headers are there. Try 
looking in /usr/include/asm.default and seeing whether they try to do 
the right thing and select the right unistd.h for the environment.
