I didn't find a clear answer as code seemed ok, so i tried to issue the
command:
../../tools/winegcc/winegcc  -B../../tools/winebuild --sysroot=../.. -shared
./windowscodecs.spec bmpdecode.o bmpencode.o clsfactory.o converter.o
gifformat.o icoformat.o imgfactory.o info.o jpegformat.o main.o palette.o
pngformat.o propertybag.o regsvr.o stream.o ungif.o    version.res    -o
windowscodecs.dll.so  -luuid -lole32 -ladvapi32 -lkernel32
../../libs/port/libwine_port.a
adding a simple -lpng:
../../tools/winegcc/winegcc  -B../../tools/winebuild --sysroot=../.. -shared
./windowscodecs.spec bmpdecode.o bmpencode.o clsfactory.o converter.o
gifformat.o icoformat.o imgfactory.o info.o jpegformat.o main.o palette.o
pngformat.o propertybag.o regsvr.o stream.o ungif.o    version.res    -o
windowscodecs.dll.so  -luuid -lole32 -ladvapi32 -lkernel32 -lpng
../../libs/port/libwine_port.a
and it magically works ok

so the previous patch just has to add png to the imports in Makefile.in to
make it work
Should i send the now correct patch?
