adapt Solaris fix for C11 changes from xterm #325.
modify parseArgs to check for a special case, e.g., from xterm,
where a shell command that cannot be exec'd is passed as a
single parameter. For that case, run the command via the shell.
reset IEXTEN when turning off canonical mode, needed to make
lnext control/V work consistently on BSD platforms (report/patch
by Christian Weisgerber).
updated configure macros:
CF_FUNC_POLL
add a fallback to checking with posix_openpt(), in case
someone's running the configure script in batch mode.
CF_LD_RPATH_OPT
change FreeBSD to use -Wl,-rpath rather than -rpath option.
According to FreeBSD #178732, either works since FreeBSD
4.x; however scons does not accept anything except the
-Wl,-rpath form.
CF_WITH_MAN2HTML
use configured shell rather than /bin/sh
CF_XOPEN_SOURCE
add a case for OS/2
update config.guess, config.sub
