8cc7fdb834 "evil" workaround to the alignment issues: embed an ALLOC_ITEM into 
struct env (other structures defined have no "foreign type with pos-
sible alignment constraints" members) and take care of it while dea-
ling in a struct env instance

c841d1513d of *course* I had to introduce an inverse-logic error 
d'oh. the XOR check's result needs to be reversed, as it tests for validity

31d2796169 simplify 
if ((flags & (1 | 2) == 0) || (flags & (1 | 2) == (1 | 2)))
to
	if (!(flags & 1) ^ !(flags & 2))
which works because ! returns 1 or 0, making the ^ an ^^, and
because XOR survives NOTting its arguments

9e83002841 try to do some optimum struct packing except for struct env 
(pointers, longs, size_t first; time_t next; int etc. then enum, bool)

c7ccde864e apply workaround given to me in IRC yesternight, just define away the 
const keyword to not trigger the famous ACK const bug (no chance it’ll
get fixed, not even in Minix 3’s ACK version)

e88736b5ef decouple conservative file descriptor use from MKSH_SMALL, with the 
new MKSH_CONSERVATIVE_FDS præprocessor flag, because Minix 3, for

5bfb6c97df remove extra parenthesēs; the error on WIFSIGNALED is still there:

db6ed8be7c ... and it did in fact require DEC ucode cc to spot this! 
gcc, SUNWcc, pcc, llvm-gcc, clang, etc. all didn't say a thing!

now compiles warning-free (testsuite pass) on ULTRIX 4.5 (1986),
and OSF/1 X2.0-8 (testsuite norun: perl missing) has only the usual
bitchings about "volatile sig_atomic_t" because the latter part is
already volatile, but otherwise warning-free compile, works fine

edf126c810 just assume realloc(NULL, n) is ANSI C89 (for n>0) but provide a 
define to do otherwise; shrinks the code and optimises for speed

ebfce0fafd we do not need the group backpointer, except for a (very little) amount 
of sanitising; since this is supposed to be the lightweight allocator,
with the guarding allocator coming back in later, remove it

reduces memory consumption below what espie's allocator used ☺

c37c7aea61 document somewhat surprising behaviour 
12:58⎜<gps23:#ksh> someone please tell me why:   code=1; if [ "code" -eq 1 ] returns true
13:10⎜<mira|AO:#ksh> hm but I see the problem
13:10⎜<mira|AO:#ksh> code=1; x=code; [ "$x" -eq 1 ]
13:10⎜<mira|AO:#ksh> this is indeed unexpected
13:10⎜«pgas:#ksh» gps23: code=1+1;[ "code" -eq 2 ] && echo true #also works
as of now, we consider
13:13⎜«pgas:#ksh» gps23: when you use -eq there is something like an implicit $(( )) around the
     ⎜    arguments
13:14⎜«pgas:#ksh» [ code -eq 1 ] is the same as [ $((code)) -eq 1 ]
to be documented.
