I presume the ("I had to put this line for some other reasons") is
your comments, and doesn't appear in the source.
Probably strchr is defined as a function-like macro whose definition
uses some non-standard extension called "__extension__".
The way to get the declaration for strchr() is "#include <string.h>".
Why do you need to declare it yourself?
