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,

That's defined in unistd.h, which is newlib territory. Care to send a
patch to the newlib mailing list?
Thanks,
