and pull out the patch that is difference between 1.4 and 1.5 of the
file sp26/system.h. It was never merged on the 4.5.0 branch but
fixed in Nov 2001.

Use CVSweb to browse the history for the ERC32 BSP. In particular look
at the .h files. I think the fix was tracked as RTEMS GNATS PR80 at
http://www.oarcorp.com/cgi-bin/gnatsweb.pl (use guest/guest).
I saw this fix as between version 184.108.40.206 and 220.127.116.11 of
on the 4.5 branch and between 1.12 and 1.13 on the mainline.
I hope getting the fixes from RTEMS source code control repository makes
management happy. :)
What are you guys doing with RTEMS?
