Severity: normal
Dear Maintainer,
* What led up to the situation? I was building a robot, and needed a raspberry pi zero to send a floating point number formatted as a string to an arduino.
* What exactly did you do (or not do) that was effective (or
ineffective)? I've tried passing bigger numbers than 1.0 (like 100.0) , but it didn't seem to do anything different, "%F %F" does however seem to get the second argument right.
* What was the outcome of this action? It printed out something like: -0.000000001 1.0
* What outcome did you expect instead? 1.0 0.0
Also I'm sorry if I'm doing something wrong in the bug reporting process, this is my first time using this reportbug program.

Further off-bug discussion revealed that it was a case of a
-Wimplicit-function-declaration warning and a missing prototype.
The test program was compiled without _GNU_SOURCE.
