Under Solaris 2.4, as I recall, these five were considered BSD-specific 
and non-standard, supported only with the BSD compatibility package 
(/usr/ucb/cc, /usr/ucbinclude, and /usr/ucblib).  The conventional
wisdom as I heard it was to use memset, srand, memmove, rand, and strchr,
respectively, instead of these five.  Often this could be achieved via
compiling with -DSVR4 or -DSYSV, if the code was setup appropriately, 
or by defining your own macros, like
	#define index(s,c)  strchr((s),(c))
to do the translating.  I'm not familiar with the pgperf code, though,
so I can't say what the best solution might be.

It looks Solaris 2.5 has changed this by now including these five BSD 
functions in its standard library, so it's yet another reason to
upgrade I guess. :)
