Yilmaz,

The fill nodata support was not really fully finished in 1.6, and it
seems it was accidentally omitted from the windows makefile.  I see it
is in the unix GNUmakefile.   You can try it from 1.6, but you are better
off doing it in the 1.7/trunk tree if you want something dependable.

There are a bunch of library interfaces that are considered to be internal
to GDAL and these are generally declared with CPL_ODLL instead of CPL_DLL.
If you add:

#define CPL_OPTIONAL_APIS 1

in gdal/port/cpl_config.h or somewhere else appropriate it should cause
these interfaces to be exported from the GDAL DLL instead of being hidden
as they are by default.  I have confirmed this includes the iso8211
interfaces.

It would appear the local makefile targets for building a DLL are out of
date and would need some TLC to build standalone.
