Hi Honza,

    It looks like cgraph_fnver_htab defined in cgraph.c is not added
to gc root in gt-cgraph.h. This patch fixes it.

* cgraph.c (cgraph_fnver_htab): Move GTY((...)) to be before htab_t.
Change param_is to use
the struct and not the pointer to the struct.

 /* Hash function for cgraph_fnver_htab.  */

Ok to submit?

Thanks
