Which tells me that <strings.h> is not included -- a bug that I also
ran into when I tried to compile this program. I'm told by the author
that it is fixed in the latest development sources. (It's not as
simple as just adding `#include <strings.h>', because the program
comes with its own header also called "strings.h", and passes
-I flags to the compiler that make it impossible to see the system
version.)

You have now implicitly declared the function, so the compiler now
has a declaration in scope when compiling line 116.
