The map cannot be downloaded, but so interesting, did you even try the NULL texture, this can cause almost the same...the faces which has NULL texture are completily stop out from the compile process, as I know SKY can be used as like 'NULLing'...
Srceenshot of my cs1.6 icon's property:

before doing anything my destination (or what, just see the picture) looks like this:
"C:Program FilesCounter-Strike 1.6hl.exe" -game cstrike
add to the end of it:
-console +gl_wireframe 1 +r_speeds 1 + developer 1 +map de_dust
When launch the icon (cs 1.6 from the desktop) it is automatically start to create a server with de_dust...replace de_dust with your map name...
