I don't have that CD.  Unlike Yggdrasil, they have not given me a
free copy of it.  I have not seen any other bug report about the
Posgres as it is on the DLD CD, though.

I do not know exactly, what is going on.  My guess is, that the
reason for the problem is caused by the handling of atof():

- Older versions of the linux C library had atof() unconditionally
  defined as a macro, that calls strtod() instead.
- Newer versions only define that macro, if optimization is
  turned on.
- No macro is defined, if you do not include the <stdlib.h>
  header file.

An atof() function should be defined in the C library, though.
The dynamical loader should link in that one, if it is needed.
Maybe, they have put outdated library stubs on your CD.  Try
compiling (without optimiser!) and linking a simple function,
which uses atof.  If that fails, too, their CD is the problem,
not postgres.

To get circle.c compiled correctly:
- Make sure, it includes <stdlib.h>
- Compile it using the -O or -O2 optimiser flag.
