Because only the configure macros of spot::srand() had been updated to
the introduction of _config.h, rand() was used even if drand48() was
available, and yet srand48() was being called by spot::srand(). The
consequence is that setting the seed with srand48() had not effect on
the value returned by rand(). Reported by Etienne Renault.
