Subject: Use AC_CACHE_CHECK instead of AC_CACHE_VAR.
X-Git-Tag: OPENLDAP_REL_ENG_2_BP~43
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=095f78b39282435b816ebcf68a0d72d89273986a;p=openldap

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.
