[lib] Add support for Sun libc printstack to zlog_backtrace_sigsafe
2006-05-28 Paul Jakma <paul.jakma@sun.com>
* configure.ac:
Check for Sun libc printstack(), add a general HAVE_STACK_TRACE
define for lib/log.c, if any supported stack symbol dumping
function is found (glibc backtrace/sun libc printstack).
* log.c: (general) Add support for Sun libc printstack().
(hex_append) make the cpp conditional on general HAVE_STACK_TRACE
define.
(zlog_backtrace_sigsafe) Ditto. Add printstack() version of the
the DUMP macro in this function.
