PATCH: adding invoking_program to plugin_gcc_version

[Basile Starynkevitch]

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-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.
