Description of problem:
Rebuilding jfbterm (,which I maintain on Fedora) fails
on F-8 and rawhide.
http://koji.fedoraproject.org/koji/taskinfo?taskID=271418

After some investigation, the code failing to build could
be shortened as below:
TEST-memmove.c :
----------------------------------------------------------
#define __USE_STRING_INLINES
#include        <string.h>

int main(){
	return 0;
}
----------------------------------------------------------
$ gcc -O2 -Wp,-D_FORTIFY_SOURCE=2 -o TEST-memmove TEST-memmove.c
In file included from /usr/include/string.h:428,
                 from TEST-memmove.c:2:
/usr/include/bits/string3.h:58: error: redefinition of ‘memmove’

Is this expected?

Version-Release number of selected component (if applicable):
glibc-2.7-2
gcc-4.1.2-33 (F-8), gcc-4.1.2-35 (rawhide)

How reproducible:
100%

Additional info:
This code doesn't fail on F-7.
