***** Notes *****

When programs that contain mathematics routines are compiled, the
mathematics libraries must  be called specifically on the cc com-
mand line.   For example, to compile  the example presented under
the entry for acos, use the following cc command line:


          cc -f acos.c -lm


The -f  option links in  the floating point  routines for printf,
while the  -lm option links  in the mathematics  libraries.  Note
that the -lm option must come last on the cc command line, or the
library will not be searched properly.
