[ECOS] issue in building redboot while porting to leon

[Harish Kulkarni]

Hello Group,
 
We are trying to port redboot on leon v8 processor
based board.
 
Is there any redboot patch for eCos on leon v8?
 
We are as of now using the patch ( ment for NIOS based
sparc v8) from 
the following link.
 
http://emsys.denayer.wenk.be/empro/leon2-redboot.diff
 
This patch uses sparc-rtems-gcc compiler, and we want
to use 
sparc-elf-gcc compiler, after installing the patch of
eCos 2.0 version,
 
we were able to use ecosconfig and configtool to get
to build 
environment, were after some changes we were able to
compile using 
sparc-elf-gcc, but found following issues;

These are not too serious. When you upgrade from the old 2.0 to the
latest anoncvs version these will go away.

This is bad. You cannot build eCos without this.  You need to find a
different version of the compiler which supports this. Try:
