I have to correct myself. Probably due to different incompatible ASM 
compilers, you have to set the LANGUAGE property of each ASM file with e.g.
  set_property ( SOURCE MyAsm.S PROPERTY LANGUAGE ASM )

It does _not_ work without that.

I found a bug with CMake-2.6.1 with this: a -Dasmtest_EXPORTS is given to as 
and my as from gcc-4.1.2 doesn't like that at all (aborts with an error).
Strangely, all other defines from the COMPILE_DEFINITIONS property are _NOT_ 
given in the as call (another bug, I assume).
