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.

Thanks,
