[Bug 22286] New: GetShortPathName -> GetLongPathName doesn't give back same file

http://bugs.winehq.org/show_bug.cgi?id=22286

Summary: GetShortPathName -> GetLongPathName doesn't give back
                    same file
           Product: Wine
           Version: unspecified
          Platform: x86
               URL: http://cmake.org
        OS/Version: Linux
            Status: NEW
          Severity: normal

Some people are using a cmake/mingw/msys/wine combination on Linux to
compile/test code targeting Windows, and its currently being discussed on the
cmake user's list.

CMake uses a GetShortPathName() / GetLongPathName() trick to get the actual
case for a filename.

If the a directory contains these two files (from a CMake installation, but can
be empty files),
CMakeFortranInformation.cmake
CMakeTestCXXCompiler.cmake
and GetShortPathName()/GetLongPathName() is called for
CMakeTestCXXCompiler.cmake, it returns the other file instead.

======

#include <windows.h>
#include <stdio.h>

int main(int argc, char** argv)
{
  if(argc < 2)
  {
    printf("Usage: %s filename\n", argv[0]);
    return 1;
  }

char buffer[MAX_PATH+1];
  char buffer2[MAX_PATH+1];

GetShortPathName(argv[1], buffer, MAX_PATH+1);
  GetLongPathNameA(buffer, buffer2, MAX_PATH+1);
  printf("%s\n", buffer2);

return 0;
}
