I have checked, the problem exists.
If someone calls a function returning a double without having provided a
prototype, the result is considered as int then casted to double.
The result is totally wrong, and by default GCC issues no warning :-(

> -Wmissing-prototypes

Useless.
This warns the author of a function if he forgot to provide a prototype in
its .h, but does nothing if the user forgets to include the .h.

> -Wstrict-prototypes

Useless.
This warns the author of a function if he has provided an old-school
prototype, without arguments. No effect on the user.

Please test your tips.

However:
-Wimplicit-function-declaration warns the user if he forgot the include
file. If there is no warning, he can be sure he will not have trouble
because of functions returning doubles.
-Wall would be usually better, as it includes this warning and many others.
