Clang and windows headers


Trying to compile a C++ source file including windows.h header with clang++, fails with

#error Must define a target architecture


For example,


$ cat foo.cxx
#include <windows.h>

int main()
{
  return 0;
}

$ clang++ -c foo.cxx -o foo.o

Really I have seen this the first time trying to build the next release of ROOT (i.e. source from svn; the main page for ROOT is : http://root.cern.ch).


Indeed now ROOT uses clang tools to build (GCC is used to bootstrap ROOT's patched version of CLANG...). Nevertheless the same errors occurs using Cygwin's CLANG as the above simple test case shows...


Ciao, Angelo.
