• use DOWARN semantically correct
• support the Microsoft® C Compiler
• on Interix, disable msc's security checks, as it relies on
library functions not provided by Interix' libc (XXX mirtoconf this)
namely Dr. Robert “Pfeffer” Arnold (in this case, in FreeWRT), make
a half-completed attempt at implementing ${foo:2:3} substring evals
(of course, negatives can't work right now and that the numbers are
in face expressions is something I only read later too – this is to
be revisited later, but it's already late)
don't depend on this behaviour yet though
if someone wants to add more regression tests, feel free to…

still work to do for HP C on IA64
is a compromise anyway; these lunox people will have to live with that, too
many existing korn shell alike scripts depend on it even if not on the full
korn shell syntax availability (note: this doesn't mean using these in some
script with #!/bin/sh is ok)
problems. icc's warnings are bogus:
• it says int x_getc(void); is invalid (hm well, it may be static?)
• char c, d; d = c | 0x40; -> warning because (c | 0x40) is an int
(it apparently can't track value bounds)

this one is muuuuch too verbose IMHO, _and_ it #defines __GNUC__ (eek)
any more either, and can make use of code sharing between detection
of sys_siglist and sys_signame (and the underscored variants); nuke
the now-useless signames.c file too (merge struct into histrap.c)
SIGABRT to SIGIOT (good), SIGCHLD to SIGCLD (necessary and reason),
SIGIO to SIGPOLL (the former also exists on mirbsd so okay); changes
on other OSes should be monitored by porters
