+Subject: [PATCH] Provide an alias to _obstack_free
+
+GDB 7.11 does not build if compiled against uclibc-ng (1.0.12 was used,
+but the problematic code exists in 1.0.13 as well). The reason is that
+GDB release includes its own obstack implementation, but elides the code
+if <gnu-versions.h> declares a compatible obstack implementation in
+libc. uclibc-ng does claim compatible obstack interface (GDB expects
+version 2, but accepts version 1 if sizeof(int) == sizeof(size_t)),
+however, uclibc-ng does not provide the _obstack_free symbol that is a
+part of the interface (glibc does provide this symbol). This later
+causes a link failure.
+
+The attached patch makes uclibc-ng enables an alias _obstack_free ->
+obstack_free.
