+Description: Fix segfault by including a missing header file
+ Without the header file, the compiler had no way of knowing what the
+ functions get_rdfileopt() and get_wrfileopt() looks like and as a result
+ it did an implicit declaration and assumed they returns an integer
+ instead of a pointer.
