Hi, I am trying to configure the build-process of the pjlibs with clang, to support the new iPhone5s' 64bit-architecture. I am uncertain, what the appropriate architecture-identifier is (e.g. armv7s, armv8 ?), or, if any additional settings or provisionings are needed in order to aid "configure-iphone" to accomplish this (i.e. 64-bit support on iPhone 5s). Thanks in advance! Regards, -Thomas
