Issue with getline in Cygwin

[urbster1]

I get these errors when trying to compile in Cygwin:

In file included from boggle/boggle/bog.c:58:0:
boggle/boggle/extern.h:46:7: error: conflicting types for ‘getline’
 char *getline(char *);
       ^
In file included from /usr/include/ctype.h:4:0,
                 from boggle/boggle/bog.c:49:
/usr/include/sys/stdio.h:35:9: note: previous declaration of ‘getline’ was here
 ssize_t _EXFUN(getline, (char **, size_t *, FILE *));
         ^
make: *** [GNUmakefile:158: boggle/boggle/bog.o] Error 1

If I comment out this line in /usr/include/sys/stdio.h ssize_t _EXFUN(getline, (char **, size_t *, FILE *));

then I get this error:

cribbage/io.c: In function ‘getline’:
cribbage/io.c:543:9: error: lvalue required as left operand of assignment
  stdscr = Msgwin;
         ^
cribbage/io.c:580:9: error: lvalue required as left operand of assignment
  stdscr = oscr;
         ^

Any way to find out how this could be made compatible? It's Cygwin 64 bit if that matters.

I had the same problem too, but I found that this problem happens only on dm, banner, boggle, cribbage, fortune, factor, gomoku, hack, hunt, mille, monop, morse and robots, so I excluded them from the build
