link: fix test to declare use of rename() The test in link.m4 needs to include <stdio.h> to provide a declaration for the rename function. The test fails if building with GCC's -Werror=implicit-function-declaration option. This was reported as part of a bug with building Octave on Fedora, which now uses -Werror=implicit-function-declaration by default. * m4/link.m4 (gl_FUNC_LINK): Include <stdio.h>. https://savannah.gnu.org/bugs/?49782
