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
