* configure.in (AC_CHECK_FUNCS): Add ctermid, setpgid, setsid, tcgetpgrp, tcsetpgrp, and waitpid to the list of functions to check for. * configure, scmconfig.h.in: Updated, using autoconf and autoheader. * posix.c (scm_sys_ctermid, scm_sys_setpgid, scm_sys_setsid, scm_sys_tcgetpgrp, scm_sys_tcsetpgrp, scm_sys_waitpid): Put the bodies of these functions in "#ifdef HAVE_MUMBLE" clauses, with a stub that signals an error as the #else.
