20100709 maxb Approved
20100709 maxb It looks like we'll need the LOSAs to manually accept the ssh host key, suspending for now - pending https://answers.launchpad.net/launchpad-code/+question/117193
20110610 mirabilos Imported fine, thanks!
20120216 mirabilos Fixed server-side error w.r.t. the modules file, import may be unfailed again

better rlim_t-replacement determination and diagnostics

I recently managed to hit “j_async: bad nzombie (110)”, but this is
probably when other processes are “reparented” to mksh perhaps as
(relative) pid 1, so move it to #ifdef DEBUG

advance mbsd{int,cc}.h quite a bit:

• move mksh/sh.h SHIKATANAI macro to mbsdcc.h and test it (bt-normal)
• mirtime: note Issue 8 changes needed
• C++ mbccChkExpr/mbccCEX now work with both OpenWatcom C++ (targetting
  Linux/i386), antique G++ and SUNWCC (Sun Studio 12.6), too
• C++ mbccFAMslot now works outside GCC/Clang/MSVC++ (“works”, [1] hah)
• OpenWatcom C: disable warning “Comparison result always 0” during CTA
  (downside is that ending a CTA should restore the level, but it lacks
  a pop pragma, so we set the level to 4/info)
• for all bitfields, use unsigned int because SUNWcc complains about
  nōn-portable bitfields, C89 allows only {,{,un}signed} int anyway
• better consistency checks in mbCTA_END
• -DMBSDINT_H_SMALL_SYSTEM=3 handles 64-bit types again but works in a
  16-bit environment (OpenWatcom C targetting DOS, where I got the
  selftests to work but the whole testsuite won’t fit a segment, or
  even multiple at once, we’re going to have to hack that eventually)
• -DMBSDINT_H_WANT_LONG_IN_SIZET=0 for 16-bit without size_t ≥ long
• change mbiTYPE_ISF to work in OpenWatcom C++; as that works in CTAs,
  mbiCTA_TYPE_{NOT,not}F goes away
• work around MSVC ignoring (unsigned)sizetvar casts for -Wformat by
  writing them as (0U + (unsigned)sizetvar); their rationale is to
  make users switch to %zu ofc but we can’t do that in ancient C
• check bc(1) is usable near testsuite runner beginning
• rename all files to not have more than one dot, for OpenWatcom/DOS
• check the “whether we can build at all” result if it runs unless cross
• also check the split compile and link step works
• check for <float.h> for the testsuite’s system info helper and make
  it show float, double and long double info if present
• split tif() from ti(), the latter “probably” fails compilation, in its
  int parts, if a type is actually float; tif now uses some bounds checks
  against the type-maximum and max-const deferring mbiMASK_BITS (and the
  mbiMASK_BITS part of mbiTYPE_UBITS) into a function instead of inline
  so the constant folder does not explode (also uses a volatile variable
  for the same purpose) but this is just so we can go without configure-
  time type checks exclusively in the system info helper
• time_t could be float outside of POSIX land, use tif to info it
  (CTAs check other (shown) types to be integral)

more crosslinks and an update on the ksh situation

fix for tracing when not run under dash (oops, eval)

I wonder why I did not do this in the first place… vaguely remembering
having some kind of trouble with it but…

address users’ requests for C-style “for” loops by showing “while” loops

make time callable as a builtin

more portability work thanks to RT

• retire MKSH_TYPEDEF_SSIZE_T, define SSIZE_MIN/SSIZE_MAX/ssize_t via
  cpp and early, so mbsdint.h et al. can use it as well
  ‣ this is probably still needing work (e.g. could autodetect-ish it),
    maybe when mirtoconf’ing the mbsdint testsuthe
• try to detect SCDE (Standard C Development Environment) as compiler
  on SINIX and SVR4
• default CC to 'cc -Xa' on SINIX and (for now) SVR4
• Dell UNIX (SVR4) has no ssize_t, either
• GCC/Dell UNIX needs -U__STDC__ -D__STDC__=0 to find NSIG
• drop remnant of older NSIG hack
• refresh MirBSD Makefiles

apply “typeset -p” bugfix from Martijn Dekker

also add a dummy test in front of fastbox test so users know

make asciibetical() consistently return KUI type, document its max range

(it must be KUI, not KBY, as in EBCDIC it ranges up to USHRT_MAX (probably
at most 0x1FFU though), which is safe to use in subtraction comparison)
