Thanks.  I already killed them locally though.

By waiting for the fix for PR bootstrap/19364 to be commited. :-)  This patch 
is only a preliminary cleanup.  I want to remove as many useless macros as I 
can before the big one.

I'll provide default values in the new sparc-elf configuration file.  You 
should not have to change anything in rtemself.h.

OK, thanks.  And any GDB version should work, DWARF-2 on SPARC 32-bit has 
been supported for ages.
