By andersk:

All arguments to m4 macros should be quoted.

The `AC_MSG_ERROR` could just be the third argument to `AC_PATH_PROG` instead of going in a separate `if` statement.

If you’re using `AC_PATH_PROG`, you should also remove `PROTOC = protoc` from src/protobufs/Makefile.am so that the full path can be picked up from configure.
