Sorry, but your code is buggy. You *must* prototype atof before using 
it, otherwise the default return type in C is "int" and obviously you 
get garbage in this case. Either include <stdlib.h> or declare it 
yourself.

  $ gcc -c -Wall file.c

is a good check before blaming the compiler ...

Also, you probably should upgrade your compiler tools to egcs. See
Cygnus home page for link back to mine.
