if we find any, but not later; do not check on every read
⇒ allows changing COLUMNS and LINES (independent of each other, or both)
for script shells by passing them in an environment setting, even if
we get a tty; interactive shells still check before each line is read…
reported by the PLD guys, thanks
prerequisites are actually fulfilled, i.e. evrn further down than with
the last commit doing this, and move some prerequisites of stuff that
has wandered outside the !INCLUDES_ONLY block with the compile-time
assert changes to the outside, too
fixes FTBFS on MSYS which has neither <stdint.h> nor uint32_t
reported by RT
handle any more, octal 010 style constants, as promised
• overhaul the manpage re. arithmetic expressions, make the guarantees
mksh code has explicitly, precisely, clear
• to reduce burden of the compiler, getint() now operates on mksh_uari_t
internally; it already applied the sign after operation, anyway (C99
guarantees wraparound on unsigned types, but for signed types we need
specific compiler support; apparently, this comes from hardware limits)
• use const and shuffle order of locals around while here
in the cases where they are defined unambiguously; bug reported by
Jilles Tjoelker in <20111129232526.GC14357@stack.nl> due to a report
by Stefano Lattarini on bug-autoconf
in the ambiguous case, I stick to traditional pdksh behaviour, which means
test ! a = b vs. test a = b
and
test ! a -o b vs. test a -o b
behave different from each other (in the second case, the NOT operator
binds strong; POSIX demands a reduction to 3 arguments and negating
that result in the first case), so we're at two known not-ok in the
FreeBSD® testsuite. (81 and 82 in regress.sh,v 1.3)
move /etc/{,suid_}profile to /system/etc/ for Android (but do not make
the location of /etc configurable); rewrite manpage section about
/etc/{,suid_}profile, .profile, .mkshrc
• while here, reformat 'struct tbl' comment-wise and placement-wise
and drop the Tflag typedef
• while here, write regression test for the "global" built-in, which
does what typeset is supposed to do except that it doubles as "local"
