Protoize does not build with gcc 4.x

[Andreas Krebbel]

Hi Richard,

the protoize utility can't be built with gcc 4.x.

Your patch "Using .opt files for target options"
http://gcc.gnu.org/ml/gcc-patches/2005-03/msg01297.html

makes options.h to be included by tm.h by adding it to tm_include_list
in gcc/configure.ac. tm.h is included by protoize.c. That leads to a name 
clash between the "version_flag" and "quiet_flag" symbols defined as 
extern in options.h and defined static in protoize.c.

Could you please look into this.

Bye,

-Andreas-
