+Subject: [PATCH] configure.ac: Avoid implicit int, implicit function
+ declarations
+
+Do not call exit without declaring it.  Add #include <unistd.h>
+for fork.  Add missing int type to the definition of main.
+
+Implicit ints and implicit function declarations were removed from
+C in 1999 and will not be supported by future compilers.
