The wording of a small number of errors relating to the subtyping of capabilities were improved. These were previously technically incorrect, or otherwise unnecessarily obtuse.
Building on 64-bit Raspbian needs the flag -fPIC instead of -fpic which is used by default on Unix builds.
We've added a Makefile flag pic_flag that you can set to either -fpic or -fPIC for both libs and configure steps, e.g. make libs pic_flag=-fPIC and make configure pic_flag=-fPIC. It will default to -fpic if not specified.
We've gotten Pony building on 64-bit Raspbian running on Raspberry Pi 4 model B boards. The installation is a little different than other Linux distributions that you can build Pony on, so we've added instructions specific to 64-bit Raspbian.
