[vtkusers] error: cmake + free optimizing compiler from .net framework SDK --- x86 conflicts with x64

[Weiguang Guan]

Hi Mathieu,

I am working directly on Windows XP rather than on Cygwin layer. I think 
this might be a cmake issue, because the error message box appears after 
I hit the "Configure" button of CMake, and the same error message pops up 
when configuring an ITK build with cmake.

The error message seems coming from CMakeTestCCompiler.cmake, in which a 
simple c program (see below) is generated on the fly and compiled.

#ifdef __cplusplus
# error "The CMAKE_C_COMPILER is set to a C++ compiler"
#endif
#include <stdio.h>
#if defined(__CLASSIC_C__)
int main(argc, argv)
   int argc;
   char* argv[];
#else
int main(int argc, char* argv[])
#endif
{ printf("%s\\n", argv[0]); return argc-1;}

I manually saved it into a file and got it compiled and linked. It worked 
fine. Can anyone explain why cmake thinks "it is not able to compile a 
simple test program"?
