Bug #1711: memmem() in string.h should be more or less VISIBLE on x86_64?

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.

Suppose on x86_64 some package, say scmgit-base, detects the existence of
memmem() yet because it too  does not define any *VISIBLE uses an implicit
definition of memmem(), as is indicated in the build messages:

    checking for memmem... yes
    checking for library containing memmem... none required
and
    
    diff.c:369: warning: implicit declaration of function 'memmem'
