As you may already know both GDAL and MapServer had a new stable release in the recent days and I've updated http://vbkto.dyndns.org/sdk/ to provide the Windows binaries according to these versions.
If you prefer using the latest stable releases (GDAL 1.8.0 and MapServer 5.6.6) then choose the 'release' packages, but you may also download the most recent daily builds of the stable branches (always containing all the subsequent changes since the last release) by choosing the 'stable' packages.
The development versions of GDAL and MapServer are also available for testing by using the 'development' packages.
I've also added Windows installers for the GDAL components providing to install the GDAL command line tools and the python bindings easily. Installers for MapServer with IIS registration and PHP support will also be available shortly.
