just put the .def file in with the list of .o's to be included in the
dll.

w32api is the place where Win32-specific #include files are stored. 
Cygwin puts them there to keep the separate from the 'cygwin' #include
files.  These files are used by cygwin gcc, cygwin-gcc with -mno-cygwin
switch, and by mingw gcc (although the mingw distro puts them somewhere
else).

-mno-cygwin turns the cygwin gcc into a cross-compiler,
host=i686-pc-cygwin and target=i686-pc-win32.

mingw is a totally native version of gcc for win32.  Not even gcc.exe
from the mings distro depends on cygwin1.dll.  Thus, host=i686-pc-win32
and target=i686-pc-win32.
