New Revision: 231101
URL: http://svn.freebsd.org/changeset/base/231101

Log:
  In usr.bin/rpcgen/rpc_main.c, use execvp(3) instead of execv(3), so
  rpcgen will search the current PATH for the preprocessor.  This makes it
  possible to run a preprocessor built during the cross-tools stage of
  buildworld.
