Hi,

building gdb-6.8.91 for sparc-rtems* (sparc-elf) on F11/x86_64
raises this warning:

/usr/include/bits/string3.h:52: warning: call to __builtin___memcpy_chk

The patch below is what I am including into the rtems-gdb patches.

I don't have write access to gdb-cvs, and would appreciate it, if 
somebody else would apply the patch for me.

TIA,
