Some type definitions in sparc/include/ansi.h have been changed to
match those used by the sparc64 port. This allows better sharing
of the toolchain. No binary incompatibility is introduced by this
change. However, the compiler must be updated because of its
built-in `size_t' type that it uses to check built-in ANSI functions
(such as the mem*() family).

This change has been timed to coincide with the move to ELF by the
sparc port to minimize the hassle of forced re-installation of
binaries that affect the build process.
