  ANSI C uses the <stdarg.h> header file to define the variable
argument interface.  ORCA/C 1.3 did not include any of vprintf, vsprintf,
or vfprintf; ORCA/C 2.0 does.

  So basically, it's there, you use a different header than BSD, and
you're stuck if you need v*printf (although there is a 3rd party 
vsprintf available, it's pretty useless without the other functions
in the set, too.)

Not exactly stuck, Jawaid . . . it may be kludge, but using the string
that vsprintf produces as the format string for fprintf or printf
makes the 3rd party version work for all three functions.

  Well, okay, agreed, but let me clarify.  With only vsprintf, you have
to either allocate a buffer or make a static buffer; and if you don't
know how long a particular string may be, you might be doing a lot of
extra work that would be unnecessary with the full set.
  vsprintf has saved my butt several times, but I'm glad ORCA/C 2.0
finally has the full set.
  [ Oh.. the one thing that really irked me about the vsprintf lib
    is that no source was included with which to make the other two. ]
