This is cmak trying to recognize which assembler this is by looking at the 
output of the assembler,

This is e.g. what GNU as says:
hammer:~$ as --version
GNU assembler (Linux/GNU Binutils) 2.21.51.0.6.20110118
Copyright 2011 Free Software Foundation, Inc.

This assembler was configured for a target of `i486-slackware-linux'.

There is then a regexp in CMakeDetermineASMCompiler.cmake, which recognizes 
this as the GNU assembler.
Does dasm.exe have a command line switch which just makes it print its name 
and version number and exit ?

This should be added to CMakeDetermineASMCompiler.cmake then.
...or you preset CMAKE_ASM_DIGNUS_COMPILER_ID to DIGNUS.

Yes. It should be much better now.
But I didn't follow that whole thread...
