+Subject: [PATCH] fix configure failed while build dir name contains "yes"
+
+While build dir name contained "yes", and compiled with
+producing debugging information (-g), the configure failed.
+
+The pattern of AC_EGREP_CPP (string "yes") mismatched with
+dir name. It caused the test of AC_EGREP_CPP incorrect.
+
+Use YES_IS_DEFINED to replace yes which is not often used
+as dir name.
+
+Bug: 52329
+(Fix release v.4.6.2 or above)

+Subject: [PATCH] [PATCH 4/4] Avoid mis-identifying systems as SVR4
+
+Linux can be misdetected as SVR4 because it has
+libelf installed. This leads to linking with libelf, even though no
+symbols from that library were actually used, and to a workaround for
+a buggy getlogin() being enabled.
+
+It is not documented which exact SVR4 system had the bug that the
+workaround was added for, so all I could do is make an educated guess
+at the #defines its compiler would be likely to set.
+
+Modified from patch by Maarten ter Huurne.
