Hello All,

The attached patch to trunk 174518 adds a field invoking_program to the
plugin_gcc_version structure. It informs the plugin about the program
"cc1", "cc1plus", "lto1" using them.

######### gcc/ChangeLog entry ##########
2011-06-01  Basile Starynkevitch  <basile@starynkevitch.net>

	* gcc-plugin.h (struct plugin_gcc_version): Add invoking_program field.

	* toplev.c (general_init): Fill invoking_program field of gcc_version.

	* configure.ac: Ditto.

	* configure: Regenerate.

See http://gcc.gnu.org/ml/gcc/2011-06/msg00000.html & 
http://gcc.gnu.org/ml/gcc/2011-05/msg00324.html for why I believe it is useful.

Ok for trunk?

Regards.
