+Subject: Fix include/stdio.h C++ incompatibility
+
+I have seen the following error when building bsdgames with
+libncurses6:
+
+In file included from /usr/include/wchar.h:36:0,
+ from /usr/include/curses.h:400,
+ from dab/box.cc:48:
+include/stdio.h:38:14: error: conflicting declaration of 'char* fgetln(FILE*, size_t*)' with 'C' linkage
+ extern char *fgetln(FILE *stream, size_t *len);
+ ^~~~~~
+In file included from /usr/include/curses.h:183:0,
+ from dab/box.cc:48:
+include/stdio.h:38:14: note: previous declaration with 'C++' linkage
+ extern char *fgetln(FILE *stream, size_t *len);
+ ^~~~~~
+GNUmakefile:298: recipe for target 'dab/box.o' failed
+
+Declaring fgetln as extern "C" fixes this. The patch has been taken
+from the Fedora bsd-games package, see
+https://src.fedoraproject.org/rpms/bsd-games/blob/ac743bec7031199ec6fc09b6eb3760ffcfcfd277/f/bsd-games-2.17-stdio-c++.patch.
