Rob gave me the sollution.
Parently the fault lies with nmake.
The version I downloaded seperately was not ok. I had to use the version supplied by Microsoft Platform SDK. Than it compiled ok (if I turn off slatec support).
That will work (slipped my mind).
Nmake1.5/MakeMaker got along for a long time, until recent (and i use the term very loosely) versions. Its too bad there isn't a small standalone download of the newer nmake floating around.
