+Subject: [PATCH] configure.ac: add AC_USE_SYSTEM_EXTENSIONS
+
+Build with gcc 4.8 will raise two errors, one on uint, the other one on
+alphasort:
+
+In file included from iprdump.c:17:0:
+iprlib.h:1866:2: error: unknown type name 'uint'
+  uint supported_with_min_ucode_level;
+  ^
+
+iprlib.c: In function 'ipr_get_pci_slots':
+iprlib.c:1999:48: error: 'alphasort' undeclared (first use in this function)
+  num_slots = scandir(rootslot, &slotdir, NULL, alphasort);
+                                                ^
+
+Fix them by adding AC_USE_SYSTEM_EXTENSIONS in configure.ac
