when parsing the type in this cast:
  (int (__attribute__(X) *)(int))foo
we ignored the attribute, which matters if it's e.g. a 'stdcall'
attribute on the function pointer.  Only this particular placement
was misparsed.  Putting the attribute after the '*' or outside the inner
parens worked.  This idiom seems to be used on SQLite, perhaps this
fixes a compilation problem on win32 with that.
