1. generate files:
    ./autogen

2. configure for win32
    ./configure --host=i686-pc-mingw32 \
        --with-ommedia=/usr/local/omneon/ommedia-win32-6.3.0.1.20110519 \
        --with-omplrlib=/usr/local/omneon/omplrlib-win32-6.3.0.1.20110519

3. preparation of library files cross-compiling

    # create def file
    pexports.exe omplrlib.dll > omplrlib.def
    pexports.exe ommedia.dll > ommedia.def

    # create lib file
    /usr/i686-pc-mingw32/bin/dlltool omplrlib.dll --def omplrlib.def --output-lib ../lib/libomplrlib.a
    /usr/i686-pc-mingw32/bin/dlltool ommedia.dll --def ommedia.def --output-lib ../lib/libommedia.a
