+Subject: [PATCH] configure.ac: more carefully detect availability of
+ res_querydomain(3)
+
+Since glibc 2.2, the function res_querydomain(3) is implemented as a
+define to `__res_querydomain`. Due to this implementation detail, using
+`AC_CHECK_LIB` with a symbol name of "res_querydomain" will cause a
+linking failure and thus fail to detect its availability. This is why
+right now, we try to detect availability of `__res_querydomain` instead.
+
+Unfortunately, this may break on other platforms where there is no
+`__res_querydomain` but only the function without leading underscores.
+To fix this, we can perform another `AC_CHECK_LIB([resolv],
+[res_querydomain], ...)` call in case where the other one was not found
+and only raise an error if both symbols weren't found.
