ITS#9348 don't declare sys_errlist if not present If HAVE_SYS_ERRLIST is false, nothing uses them anyway, so the declarations serve no purpose. Just breaks the compile if the library actually defines them (and we are avoiding using them). 2020-09-16 10:08:52 -04:00			`#if defined( HAVE_SYS_ERRLIST ) && defined( DECL_SYS_ERRLIST )`
Use AC_CACHE_CHECK instead of AC_CACHE_VAR. Rework sys_errlist detection to set HAVE_SYS_ERRLIST if sys_errlist exists. If it declaration is needed, DECL_SYS_ERRLIST is also set. 1999-07-23 20:04:05 -04:00			`/* have sys_errlist but need declaration */`
Rework <ac/errno.h> to provide a STRERROR. Prefers errlist over strerror() as strerror() may not be thread safe. Likely should be used by SLAPD. 2000-07-05 21:24:52 -04:00			`LDAP_LIBC_V(int) sys_nerr;`

actually define HAVE_SYS_ERRLIST if we have it, if not then declare it locally in ac/errno.h 1999-03-13 13:19:11 -05:00			`#endif`
