tg ddd2dac47d * support old environments without libgen.h (ancient GNU/Linux)
and stdbool.h (ancient GNU/Linux; NetBSD® 1.6.1)
* __dead must come after, not before, to accomodate gcc 2.7.2.3

tg 8fea7398d3 we need "$CC -E -" as cpp, not "$CC -E"
found on
Linux ecce 2.0.38 #1 Wed Jul 26 22:05:46 2000 i686 unknown
Reading specs from /usr/lib/gcc-lib/i386-linux/2.7.2.3/specs
gcc version 2.7.2.3

Note: during the entire compile, there are warnings like
| gcc: unrecognized option `-std=gnu99'
but these won't trigger -Werror since they are in the driver,
not in the front-end, so they are harmless, I guess. (I don't
know of a way to make them vanish, either.)

tg 8620379fcc * add #ifdef MKSH_NOPWNAM to prevent pulling in getpwnam()

tg c231ab8cc4 * order tests: we want to use correct NOWARN as much as possible
* "$e" and "echo" fixes for if the stuff begins with a -, and
  quoting cleanup (where feasible, feel free to send diffs)
* cosmetics

I hereby name this baby "Mirtoconf".

tg a00fbd3eb7 autoconf for -std=gnu99 (not c99 because of brokenness in the field)
from ankon -> solaris 10 with gcc 3.4.6 from sunfreeware
2007-01-14 21:38:25 +00:00
tg 29b62b186d okay, this didn't work out; changing window sizes when we're
actually within a (the emacs) editing mode does not work at
all, whether forced or not, only if we leave the editing mode
(at end of input); probably due to it saving stuff from e.g.
x_cols into xx_cols, etc.

-> remove SIGWINCH handling(!)
-> TIOCGWINSZ is now executed at end of every input line
-> use 'ESC #' if you direly need to change line size
2007-01-14 01:56:23 +00:00
tg 36e761840e * do *not* check the terminal size after each line processing,
only if we got a SIGWINCH -> interactive use speed-up on the
  slower boxen (slowness courtesy of otto@obsd)
* ^L (redraw line) now (always) checks window size; use this
  instead if required while editing the prompt; changes to the
  variables will still be propagated after the line is entered
2007-01-14 01:09:09 +00:00
tg 87f681b488 * revert some of the const-warning cleanup which must be done
with different means (reads, tricky magical kludgery)
  YES, THIS BREAKS -rHEAD, I KNOW.
* while here, fix spelling

tg 2c46d96042 * instead of setting LDSTATIC='' for OSes which did not support it
until now, set it to '@'
* if LDSTATIC is '@' make it '-static' if MKSH_SMALL, '' otherwise

Yep, this might break, e.g. Darwin or Cygwin. But let's test that.

tg 5891915f1b * Scan for __attribute__((...)) in general (the earliest was 2.5,
where we had 'noreturn' etc. but no '__noreturn__')
* Scan for __attribute__((bounded)) and __attribute__((used))
  if we have __attribute__((noreturn))
* To be able to scan if certain attributes give warnings,
  scan for -Werror with a simple programme which hopefully triggers none
* Convert __attribute__((unused)) to __unused, noreturn -> __dead
* Unify other attributes
* Clean up typography a little more
