+Subject: [PATCH] Allow usage of getrpcbynumber() when getrpcbynumber_r() is
+ not available
+
+getrpcbynumber_r() is not implemented by libtirpc at the moment, only
+the non-reentrant getrpcbynumber() is available. Since nfs-utils seems
+to only be using getrpcbynumber_r() is a non multithreaded context,
+using getrpcbynumber() should work just as well.
+
+We also take this opportunity to adjust the autoconf checks to verify
+whether any of getrpcbynumber() or getrpcbynumber_r() is available,
+and error out if none of them is available.

+Subject: [PATCH] Let the configure script find getrpcbynumber in libtirpc
+
+The getrpcbynumber() function may not be available in the C library,
+but only in the libtirpc library. Take this into account when checking
+for the existence of getrpcbynumber() and getrpcbynumber_r().

libtirpc does not implement the reentrant function getrpcbynumber_r(), so allow nfs-utils to use the non-reentrant version getrpcbynumber(). This should not be a problem as nfs-utils tools are not multi-threaded.
