tinyproxy/configure.ac
Robert James Kaes 3a787ecbfa Small changes to conform to the new Autoconf standards. Also, added a 
test for the OpenBSD system which prevents the inclusion of the malloc.h
header (the functions are actually defined in stdlib.h)

I might even remove the malloc.h header altogether since the malloc/free
functions _should_ be in stdlib.h
