isgraph in ucb - on MIS, where is it

[Dave Dickson]

I am trying to compile ksh88f on a Pyramid MIS (OsX 5.0d) in the
UCB universe.  It seems that isgraph() is missing from the
pyramid libraries.  Does anyone have any ideas, is this an
over-site on Pyramid's part, or do I have to write one and merge
it into the library?
