 Hello!

 My cross-compiling activity has discovered that TEMP_FAILURE_RETRY() macro
is often used, but missing in our includes. GNU code of this macro is below:
--- cut ---
# define TEMP_FAILURE_RETRY(expression) \
  (__extension__
\
    ({ long int __result;
\
       do __result = (long int) (expression);
\
       while (__result == -1L && errno == EINTR);
\
       __result; }))
--- cut ---
 This is used in elf-utils and Prelink. What about adding it ?

Kind regards,
