When merging this into gnulib I noticed the above change will
cause problems outside libc, since later code assumes that
__attribute__((xxx)) will work and this isn't true with non-GCC
compilers, or with ancient GCC.  Could you please replace the above
code with the following, instead of deleting it?

 #if __GNUC__ < 3 + (__GNUC_MINOR__ < 1)
 # define __attribute__(arg)
 #endif

That's what I did here, in the merge to gnulib:

Thanks.
