BSD/OS 2.0.1 and Zmailer 2.99.36

["Andrew P. Kokarev" <andrew@skfgvc.pyatigorsk.su>]

BSDI BSD/OS 2.0.1, shlicc2 (gcc 2.6.3 using shlibs), Zmailer 2.99.36

Nothing really major here.

1) Working mmap() test gives 'yes' if I replace (long) with (off_t)
	in two places in test program inside configure.
2) libsh/builtins.c includes sys/param.h and this makes RE_DUP_MAX
	redefined. Removed line #include <sys/param.h> because
	it's already included in hostenv.h . Now regex.h really
	undefs RE_DUP_MAX from previous param.h anf defines its own.
3) Line 387 in config.h.in contains typo in macro HAVE_VARARGS_H.
4) I got million warnings that const is redefined. I don't know
	why gcc 2.6.3 can't pass const test, I just commented out
	#define const from config.h.
5) libc/allocate.c has ALIGN macro redefined (BSD/OS has that).
	Inserted ifdef-undef-endif combination.
6) libc/strsignal.c has declaration of sys_siglist conflicting
	with unistd.h . This is wrapped with #ifndef __FreeBSD__.
	Better solution is to have configure check existence
	of sys_siglist. And it tried, but got wrong result.
	Again, (like in 1) test program has hardwired declaration
	of sys_siglist which is wrong on BSD/OS, so it never
	compiled. If test program includes right headers, there
	no need to declare sys_siglist. If that will be done,
	#ifndef __FreeBSD__ may be removed.
	
Now it compiles. Still there are problems. lseek() often is
used with long second argument (in about every program),
which surprisingly compiles but causes SIGSEGV of mailbox and smtp.
long is 32 bit, and off_t is 64 bit in BSD/OS versions >= 2.0.
