I knew I needed to test 0.63, but didn't get the time with 9/11 last week...

Nothing.

They are both implemented. Here's the relevant portions from the man page:

     Asprintf() and vasprintf() set *ret to be a pointer to a buffer suffi-
     ciently large to hold the formatted string.  This pointer should be
     passed to free(3) to release the allocated storage when it is no longer
     needed.  If sufficient space cannot be allocated, asprintf() and
     vasprintf() will return -1 and set ret to be a NULL pointer.

...
HISTORY
     The functions asprintf() and vasprintf() first appeared in the GNU C
     library.  These were implemented by Peter Wemm <peter AT FreeBSD.org> in
     FreeBSD 2.2, but were later replaced with a different implementation from
     Todd C. Miller <Todd.Miller AT courtesan.com> for OpenBSD 2.3.

Nothing in BUGS about it.

There is /usr/bin/pagesize and the function getpagesize() in unistd.h 
which return the number of bytes in a page.
