configure.in, Makefile.conf.in, autoconf.h.in: A first cut at an autoconfigure script. By running "autoconf" without arguments on munta, you get configure, which is when run produces Makefile.conf and autoconf.h. These are not used at present. conf.h, memory.h: Slight changes to get closer to the autoconfiguration scheme.

** Various configuration parameters. Their meanings are:

**
|
|
** HAVE_SYSCONF the machine has the sysconf syscall.
|
|
** HAVE_MEMALIGN the machine has the memalign libcall.
|
|
** HAVE_MPROTECT the machine has the mprotect syscall.
|
|
** HAVE_SIGINFO sighandlers are given siginfo arguments.
|
|
** HAVE_UCONTEXT sighandlers are given ucontext arguments
|
|
** and we need ucontext.h to get access.
|
|
** PC_INDEX index of PC in ucontexts.
