readlink: fix cygwin 1.5.x bug with return type On older systems, readlink returned int instead of ssize_t, making the use of readlink via function pointer harder. * m4/readlink.m4 (gl_FUNC_READLINK): Require correct signature. * lib/unistd.in.h (readlink): Use ssize_t. * lib/readlink.c (readlink): Likewise. * m4/unistd_h.m4 (gl_UNISTD_H_DEFAULTS): Add witness. * modules/unistd (Makefile.am): Substitute it. * lib/unistd.in.h (readlink): Declare replacement. * doc/posix-functions/readlink.texi (readlink): Document this.
