Accessing fields in the global_options structure from out-of-sync plugins

Hi Guys, With the annobin plugin for gcc I have a problem accessing some of the fields in the global_options structure. Although the plugin can use the macros defined in options.h, this only works if the plugin is in sync with gcc. If the plugin was built for one version of gcc, but ru
