This is OK.

The plugin-api.h file is in both the gcc and src repository.  Please
commit the changes to the copy in gcc first.  If you haven't already
done so, please send the patch to gcc-patches@gcc.gnu.org with the
comment that I had approved it.

Please make sure that http://gcc.gnu.org/wiki/whopr/driver is up to
date with this and other changes, or get Cary to do it.  In
particular, LDPT_ADD_INPUT_LIBRARY needs to be documented to explain
what sort of file name should be passed--e.g., "c" to mean the same as
"-lc".

Thanks.
