No errors, no CMakeError.log -- just null values for the SIZEOF_LONG_LONG et al.
It sets CMAKE_C_COMPILER_ARG1 in CMakeDetermineCCompiler.cmake -- but inside:
IF(NOT CMAKE_C_COMPILER)
...so it doesn't do it if you explicitly specify a C compiler, a la:
SET(CMAKE_C_COMPILER "c:/progra~1/dignus/cc.bat -fasciiout")
At least, that's how I read it. After some fumbling, I put a MESSAGE before
and inside that IF block, and only the one before gets triggered.
Related note:
It sure would be nice if --debug-trycompile copied the compiler output to
CMakeError.log. I've been forced to put a
FILE(APPEND ${CMAKE_BINARY_DIR}${CMAKE_FILES_DIRECTORY}/CMakeError.log
"Compiler output:\n${OUTPUT}\n")
in CheckTypeSize.cmake so I can figure out what's failing (not with this, since
it's just not passing the flag, but with other failures before).

It should work.
If it doesn't, search for CMAKE_C_COMPILER_ARG1 and check using
MESSAGE(STATUS ...) what happens.
What errors do you get ?
Printed and from CMakeFiles/CMakeError.log ?

"Es macht nichts" ?
The directories are ok as you see them.
