I had a similar problem with the sirrix drivers.

The new gcc compiler treats as an error if one specifies a normal string when 
a format string (in the style of printf) is expected. This warning is 
triggered by the __attribute printf (I forget the exact syntax)  for the 
prototype in the appropriate header file.

This error is fixed by inserting an extra argument "%s" where the format 
string is expected e.g.

    function proto is 

                    int myprintf( int fd, char *fmt, ...)

    and it is being called by

                    myprintf( fd,"Some string")

    which generates the warning. Fix by changing to

                    myprintf (fd, "%s", "Some string")
