For C the _Keyword notation looks more natural, than __attribute__.  Even if
it will be implemented as __attribute__, some preprocessor circuitry can
make it look like _Keyword for the programmer. So that is not the issue. 

I am all in favor of __attribute__.  gcc also supports other languages
(avr-ada.sf.net) that might profit from your extension.  The Ada front-end
already has support for __attribute__ (pragma Machine_Attribute).  Adding
memory space support in C using __attribute__ gives the solution to Ada for
free!
