More attributes on xmalloc and friends?

[Colin Watson]

If I'm not mistaken, the xalloc family of functions should have the same
set of function attributes as the corresponding functions in glibc.
glibc gives malloc, calloc, and realloc the 'malloc' and
'warn_unused_result' attributes; similarly, it gives strdup and strndup
the 'malloc' and 'nonnull (1)' attributes. 'malloc' requires gcc 2.96,
'nonnull' requires gcc 3.3, and 'warn_unused_result' requires gcc 3.4.
Could Gnulib do the same for its x* wrappers?

Thanks,
