Hi,
(CCing u-boot mailing list and Mike Frysinger)
stdlib.h is indeed missing.
EXIT_FAILURE and EXIT_SUCCESS are defined within stdlib.h, so that
explains it.
How old are you u-boot sources ? compiler.h has been introduced by:
commit 37566090766d61beef70c62986b90749920255d8
Author: Mike Frysinger <vapier@gentoo.org>
Date: Thu Jul 2 19:23:25 2009 -0400
If your U-Boot is older than that, could you please test again with the
latest possible version ? Btw, cpu_to_be32 is defined within compiler.h
Thanks for testing and reporting.
Regards,
David.

Hi David,
Thanks for your prompt reply.
The U-Boot I am using comes from the ST Microelectronics. Their STLinux
distribution for embedded devices.
UBoot appears to be at version 1.3.1 - but I'm not sure if that is an ST
version number or not.
I suspect that the problems I am having are probably best directed towards
ST themselves.
I suspect that the CRC calculation, for the 4 bytes of CRC at the head of
the environment, might be ST specific.
I will investigate further.
Thanks,
Nick Thomas

if you aren't using the master branch of the public u-boot git tree, then your
troubles should be directed to whoever is giving you the source tree you're
using
