eliminates a raft of portability issues, including whether sys_nerr
exists, whether the platform has any valid negative errnos, etc. The
downside is minimal: errno shouldn't ever contain an invalid value anyway,
and if it does, reasonably modern versions of strerror will not choke.
This rangecheck idea seemed good at the time, but it's clearly a net loss,
and I apologize to all concerned for having ever put it in.
of c.h altogether, and putting it into the only places that use it
(elog.c and exc.c), instead. Modify these routines to check for a
NULL or empty-string return from strerror, too, since some platforms
define strerror to return empty string for unknown errors (what a useless
definition that is ...). Clean up some cruft in ExcPrint while at it.
working on the VERY latest version of BeOS. I'm sure there will be
alot of comments, but then if there weren't I'd be disappointed!
Thanks for your continuing efforts to get this into your tree.
Haven't bothered with the new files as they haven't changed.
BTW Peter, the compiler is "broken" about the bool define and so on.
I'm filing a bug report to try and get it addressed. Hopefully then we
can tidy up the code a bit.
I await the replies with interest :)

According to man page under FreeBSD for sys_errlist[], strerror() should be
used instead...not sure if this will break other systems, so only changing
two files for now, and we'll see what "errors" it turns up
Subject: [HACKERS] linux/alpha patches
These patches lay the groundwork for a Linux/Alpha port. The port doesn't
actually work unless you tweak the linker to put all the pointers in the
first 32 bits of the address space, but it's at least a start. It
implements the test-and-set instruction in Alpha assembly, and also fixes
a lot of pointer-to-integer conversions, which is probably good anyway.
And now - JMP_BUF again. Is it enough, folks ?
Fixed again:
cc1: warnings being treated as errors
exc.c: In function 'ExcRaise':
exc.c:187: warning: passing arg 1 of 'Longjmp' from incompatible pointer type
gmake[3]: *** [exc.o] Error 1
cc1: warnings being treated as errors
exc.c: In function 'ExcRaise':
exc.c:186: warning: passing arg 1 of 'Longjmp' from incompatible pointer type
gmake[3]: *** [exc.o] Error 1
Now we have:
#if defined (JMP_BUF)
longjmp(efp->context, 1);
#else
siglongjmp(efp->context, 1);
#endif
