While its not by any means ideal due to the changing format of the
GDB version, the patch did have a method for a plugin to require a
specific version of GDB.
when the plugin is loaded, its passed the gdb version (from
gdb/version.in). If it decides it can't work with that version, then it
can return false and the plugin loader will say "failed to load".
This way, the weight is on the plugin to decide if it can run or not,
rather than GDB. Is that something like what you were looking for?
