 such structure and compare them field by field. It can be used by the
 plugin's @code{plugin_init} function.
 
+The version of GCC used to compile the plugin can be found in the symbol
+@code{gcc_version} defined in the header @file{plugin-version.h}. The
+recommended version check to perform looks like
