So there were quite different results in that case as well which I
think you didn't expect?
Upon closer inspection of bad_build_dir content I see this file:
bad_build_dir/CMakeFiles/CompilerIdC/CMakeCCompilerId.o
That means extraction from "a.exe" failed and CMake fell back to
trying the compiler with the "-c" option. That produced the .o
from which the compiler id was extracted. Let's verify that by
testing info.cmake in
bad_build_dir/CMakeFiles/CompilerIdC
and reading "CMakeCCompilerId.o" instead of "a.exe". Again please
report the output from both builds of CMake.
bash.exe-3.1$ pwd
/z/home/wine/newstart/4.5.2_version/ephcom2/bad_build_dir/CMakeFiles/CompilerIdC
bash.exe-3.1$ ls
CMakeCCompilerId.c CMakeCCompilerId.o info.cmake info.cmake~
bash.exe-3.1$ cat info.cmake
file(STRINGS CMakeCCompilerId.o _strings LIMIT_COUNT 4 REGEX "INFO:")
foreach(info ${_strings})
message(STATUS "[${info}]")
endforeach()
bash.exe-3.1$

Hope this additional information helps you to figure out what is going
on.
