5a8d3175cb just rcsid-sync oksh; their change was to add /* XXX 2038 */ comment 
to $SECONDS (tbh, in 2038 we’ll have more problems than just that,
which is why 64-bit arithmetics, or unlimited-precision ones, are
on the “plans” list)

1a21176cac Tonnerre Lombard’s contribution: 
[17:27:44] Tonnerre: csh: alias doch sudo \!-1 bash: alias doch='sudo $(history -p !-1)' zsh: alias doch='sudo $(fc -ln -1)'
[17:28:03] mirabilos: ?
[17:28:34] Tonnerre: Na ganz einfach:
[17:28:36] Tonnerre: % ls /root
[17:28:39] Tonnerre: ls: cannot open directory /root: Permission denied
[17:28:42] Tonnerre: % doch
[17:28:45] Tonnerre: [sudo] password for tonnerre:
[17:28:49] Tonnerre: anaconda-ks.cfg  cgminer-1.6.2-1.rf.src.rpm  rpmbuild  upgrade.log  upgrade.log.syslog
[17:28:53] Tonnerre: %

This is one of two mksh variants; the other uses a tmpfile:
alias doch='sudo mksh -c "${ fc -ln -1;}"'

Both quote correctly, unlike the above.

Maybe use $MKSH instead? (Quoted or unquoted? Hm. Probably quoted.)
Input on that welcome…

7cce9de0bc one can’t cast an unsigned int to a signed int portably either, if the value 
is larger than the positive range of the latter (implementation-defined), so
avoid them in all explicit cases and rearrange stuff and check for it

(I’m gonna have to revise lots more code…)

0f417614dd ugh, signed >> on negative values is implementation-defined 
(but, at least, not undefined, and usually right; regress-test for it)

d96c733069 looks like multiplication is also the same between signed and unsigned 2013-04-01 01:02:09 +00:00
tg
6a745a01fa begin using unsigned arithmetics internally as much as possible 
(i.e. where signedness doesn’t matter, given -fwrapv) and note
where there’s work to do; note future improvements and additions;
optimise a little

mostly untested

e141cab1ac revert cid 10050DD0C8519194AE9 and 100511FC81525949AF7 
AT&T SVR4 broke 'cc -c -o foo.o foo.c' totally

switch to an alternative method of finding out the prototypes
provided in IRC by dalias (thanks); RT says this fixes his
issues on SVR4 – let’s just ignore the ominous message from
cid 1004713D70A5362BACF about needing to be a compile-time
check unless something else pops up, I can’t think of something
that isn’t already covered

e21a2166f7 use a different approach to the $"…" problem: 
take the states that may open a string, only permit them by virtue of
moving the code out of Subst: to handle $+" and $+' at all; then add
S[Q]BRACE to that

side benefits:
• clearer, cleaner code flow
• smaller code
• better “business logic” ☺
• defuses one heavy use of duff’s device a bit
