I've added your suggestion to package.sh, this problem is solved.

but now there seems to some problems with the added gdal_config in your patch:

from package.log
[...]
checking whether to use GDAL... yes
checking for gdal-config... /osgeo4w/usr/src/grass64svn/mswindows/osgeo4w/gdal-config
configure: error: *** Unable to locate GDAL library.

if I look - after update by the osgeo4w-setup - in C:\OSGeo4W\lib there are 
following png-related files:

10.01.2009  19:29           201.398 libpng.a
10.01.2009  19:29           228.158 libpng.dll.a
10.01.2009  19:29               947 libpng.la
10.01.2009  19:29           201.398 libpng12.a
10.01.2009  19:29           228.896 libpng12.dll.a
10.01.2009  19:29               947 libpng12.la

but no libpng13.lib.

in the gdal-config of your patch in track #1271 there following lines:

+CONFIG_LIBS="$OSGEO4W_ROOT_MSYS/lib/gdal_i.lib"
+CONFIG_DEP_LIBS="$OSGEO4W_ROOT_MSYS/lib/libpng13.lib $OSGEO4W_ROOT_MSYS/lib/zlib.lib"
+CONFIG_PREFIX="$OSGEO4W_ROOT_MSYS"
+CONFIG_CFLAGS="-I$OSGEO4W_ROOT_MSYS/include"

any hint what should be changed?

best
