Warning "__restrict_arr" redefined while building libiberty/xatexit.c

[Christian Jönsson]

This was on a Debian Woody (test release) sun4m system using

binutils                           2.12.90.0.1-1
dejagnu                            1.4.2-1.1
gcc                                2.95.4-9 (Debian prerelease)
kernel-image-2.2.20-sun4dm-smp     9
libc6                              2.2.5-3


While bootstrapping gcc-3.1 I've been getting this warning:

/share2/gcc-rel/gcc/objdir/gcc/xgcc -B/share2/gcc-rel/gcc/objdir/gcc/ -B/usr/local/sparc-linux/bin/ -B/usr/local/sparc-linux/lib/ -isystem /usr/local/sparc-linux/include -c -DHAVE_CONFIG_H -g -O2 -I. -I../../../libiberty/../include  -W -Wall -Wtraditional -pedantic ../../../libiberty/xatexit.c

Is this something to be preoccupied with?
