Re: new module 'ssfmalloc'

[Bruno Haible]

Two more portability fixes are needed:
  - On Linux/SPARC, UCHAR_MAX is not defined unless <limits.h> is included.
  - On Linux/PowerPC, getpagetsize() returns 65536, which is unusually large.

        ssfmalloc tests: Portability to Linux/PowerPC and Linux/SPARC.
        * tests/test-ssfmalloc.c: Include <limits.h>.
        (PAGESIZE_MAX): Set to 65536 on Linux/PowerPC.
