Hello, The lto plugis are tied to the built GCC anyway, so there isn't much point to versioning them.
* gcc/config.host: Remove version string * lto-plugin/Makefile.am: Use libtool -avoid-version * lto-plugin/Makefile.in: Regenerate This patch has been in use with Cygwin gcc for a long time and should be pushed upstream. Patch OK?
