+Bionic C Library Issues:
+========================
+
+This document lists important known issues of various releases
+of the Bionic C library. Note that these differ from specific
+implementation choices that are documented in the OVERVIEW.TXT
+document.
+
+Currently known issues:
+-----------------------
+
+- The C library initialization will improperly run static C++
+  constructors located in shared libraries twice.
+
+Android-1.5 issues:
+-------------------
+
+- getservbyname() returned the port number in the s_port field of
+  the 'struct servent' structure in host-byte-order, instead of
+  network-byte-order.
