New submission from David Shao<[email protected]>: The memmem() function has a prototype given in /usr/include/string.h, (and /usr/src/lib/libc/string/memmem.c exists) only it is required that __BSD_VISIBLE be defined. Unfortunately a check of gcc 4.1.2 gcc -E -dM -< /dev/null | sort shows no sign of any *VISIBLE.
__BSD_VISIBLE is not a builtin. It's defined in <sys/cdefs.h> and is 1 for our default compilation environment (unless any _POSIX_C_SOURCE or similar macros are set).
