memmem is not POSIX so the system may lack it. Then libiberty will provide an implementation, but it's a "supplemental function" and not declared in libiberty.h. We need to declare the prototype to use it then. See libiberty doc at https://gcc.gnu.org/onlinedocs/libiberty/Supplemental-Functions.html. Tested by bootstrapping GCC in the following container environments on x86_64-linux-gnu: 1. "Vanilla" system with memmem in Glibc. 2. memmem removed from string.h. 3. memmem removed from both string.h and libc.so. For 3, also verified that memmem from libiberty is linked into fixincl executable. Ok for trunk? fixincludes/ChangeLog: PR other/109293 * configure.ac (AC_CHECK_DECLS): Add memmem. * configure: Regenerate. * config.h.in: Regenerate. * system.h (memmem): Declare if HAVE_DECL_MEMMEM is zero.
