Yes, now it isn't the path.

I've recorded this trace:
-------------------------
llvm[3]: Building Debug Bytecode Archive libc.bca
/bin/rm -f /C/projects/build/MinGW/llvm-4-1/Debug/lib/libc.bca
/C/projects/build/MinGW/llvm-4-1/Debug/bin/llvm-ar rcsf 
/C/projects/build/MinGW/llvm-4-1/Debug/lib/libc.bca 
/C/projects/build/MinGW/llvm-4-1/runtime/GCCLibraries/libc/Debug/atox.bc 
/C/projects/build/MinGW/llvm-4-1/runtime/GCCLibraries/libc/Debug/io.bc 
/C/projects/build/MinGW/llvm-4-1/runtime/GCCLibraries/libc/Debug/memory.bc 
/C/projects/build/MinGW/llvm-4-1/runtime/GCCLibraries/libc/Debug/qsort.bc 
/C/projects/build/MinGW/llvm-4-1/runtime/GCCLibraries/libc/Debug/string.bc
c:\projects\build\MinGW\llvm-4-1\Debug\bin\llvm-ar.exe: 
c:/projects/build/MinGW/llvm-4-1/Debug/lib/libc.bca-000000: Can't destroy 
file (hb:2): The process cannot access the file because it is being used by 
another process.
make[3]: *** [/C/projects/build/MinGW/llvm-4-1/Debug/lib/libc.bca] Error 2
-------------------------

Like before, the temporary file libc.bca-000000 doesn't exist when finished. 
But libc.bca exists.

I've put debugging text into:
-------------------------
bool
Path::destroyFile() const {
  if (!isFile()) return false;

  DWORD attr = GetFileAttributes(path.c_str());

  // If it doesn't exist, we're done.
  if (attr == INVALID_FILE_ATTRIBUTES)
    return true;

  // Read-only files cannot be deleted on Windows.  Must remove the 
read-only
  // attribute first.
  if (attr & FILE_ATTRIBUTE_READONLY) {
    if (!SetFileAttributes(path.c_str(), attr & ~FILE_ATTRIBUTE_READONLY))
      ThrowError(path + ": Can't destroy file (hb:1): ");
  }

  if (!DeleteFile(path.c_str()))
    ThrowError(path + ": Can't destroy file (hb:2): ");
  return true;
}
-------------------------

I've also attached a complete trace for this run.

Any suggestions?

Henrik.
