(SIGTSTP): Commented #undef to allow use of ^Z in shell-mode.
(SIGNALS_VIA_CHARACTERS): #defined.
* 7300.h [__GNUC__]: #define HAVE_ALLOCA.
[not __GNUC__]: #define SWITCH_ENUM_BUG, C_ALLOCA, and STACK_DIRECTION.
(HAVE_SYSVIPC, USE_UTIME): #define these.
(memmove): We don't have this; call safe_bcopy.
(CRT0_COMPILE): #define this, so we always use the system's cc.
* config.h.in: Add #undefs for HAVE_MKDIR and HAVE_RMDIR, for
configure to edit.
* sysdep.c [not HAVE_MKDIR] (mkdir): New function, taken from tar,
for use on systems lacking the mkdir function.
[not HAVE_RMDIR] (rmdir): New function, taken from tar, for use on
systems lacking the rmdir function.
* ymakefile (crt0.o): Replace the compiler and switches with the

(CRT0_COMPILE): If the system and machine description files have
left this undefined, then define it to do the same as the old

now calling the BSD[sg]etpgrp functions directly, so this library
is not needed; it just provides the BSD[sg]etpgrp functions under
the [sg]etpgrp names.
* callproc.c [IRIX] (child_setup): Don't call setpgrp this time.
It's already been called up in Fcall_process, and create_process.
Add #undefs for these.
Dyke out code requesting -lXbsd and HAVE_RANDOM for XFREE386.
* xfns.c (Fx_open_connection): Test HAVE_XRMSETDATABASE instead of
NO_XRM_SET_DATABASE; the latter isn't used any more.
* m/delta88k, m/tekXD88.h, s/linux.h, s/usg5-4-2.h (HAVE_RANDOM):
Dyke out these #definitions; to avoid conflict with autoconf.
(HAVE_SYSVIPC, BAT68K, BAT_ALLOCA): Deleted--obsolete.
(STACK_DIRECTION, HAVE_X_WINDOWS): Deleted--configure knows.
(C_SWITCH_MACHINE): Set to -ga if using the Green Hills compiler.
(LIB_STANDARD, LIB_MATH): Defined to the 68881 versions.
(LIBS_SYSTEM): -lbsd brings sigblock and sigsetmask.
