The above message contained the following:

Interesting.  The above indicates that the symbol "ssize_t" is defined,
and yet the following code:

    #include "confdefs.h"
    #include <sys/types.h>
    #include <stdlib.h>
    #include <stddef.h>

doesn't appear to contain the word "ssize_t" after preprocessing.
Superficially, this appears to be a paradox.

Let's look at the preprocessor output in detail.  Execute the command

    /bin/cc -64 -DNDEBUG -E test01.c | grep '^int' | tail

and send me it's output.  This will tell us how the preprocessor deals
with the last line ("int ssize_t;").  If and only if the last line is
"int ssize_t;", then send me the entire output.
