warning in lchown.c

[Bruno Haible]

Hi Jim or Eric,

On MacOS X, with "gcc -Wall", I'm seeing this warning:

  gcc -DHAVE_CONFIG_H -I. -I..   -Wall  -g -O2 -MT lchown.o -MD -MP -MF 
.deps/lchown.Tpo -c -o lchown.o lchown.c
  lchown.c: In function 'rpl_lchown':
  lchown.c:73: warning: unused variable 'st'

Is it ok to apply this as a fix?
