Synopsis: atof incorrect when stdlib.h not #include'd

State-Changed-From-To: open->closed
State-Changed-By: roam
State-Changed-When: Sun Jun 24 23:24:50 PDT 2001
State-Changed-Why: 
Many, many functions depend on some header file or other to be included
in order to function properly.  This has been well-documented in both
the C standard, and the respective manpages.

In this particular case, atof(3) fails simply because if there is no
prototype, the compiler assumes that the function returns int.
You might explicitly declare atof() to return double, or, much better,
you should include the appropriate header files.
