* scmsigs.c (usleep): Clean up oddities declaring usleep; since we're just using it, not redefining it, we can use a K&R style declaration here. (sleep): Declare this, too, if the system hasn't. (scm_sleep, scm_usleep): Use scm_thread_sleep and scm_uthread_sleep if they're available; otherwise, just call the system functions. * scmconfig.h.in: Regenerated.
