/* Defaulting to APCS-26 support is a legacy issue. It has been done
that way for a long time, so changing it will probably break some
people's worlds. Support for APCS-32 is now enabled as a multilib,
and at some point in the future APCS-32 may become the default.
Possibly when chips that support APCS-26 are no longer made. */
