  Fix problems with new compiler attribute checking in configure script.
  
  The last changes to ast_gcc_attribute.m4 caused some problems checking for
  various attributes, because the scope of the symbol the attribute is applied
  to can be important; this patch allows the scope to be specified for the check.
