        * fixincludes (size_t): Add support for Motorola's stdlib.h
        which fails to provide a definition for size_t.
        (fabs/hypot): Provide a prototype for fabs on m88k-motorola-sysv3.
        (strlen,strspn,strcspn return value): Handle different layout on sysV88.
        (hypot): Provide a fake for hypot for m88k-motorola-sysv3.
Fixes from Manfred.
