Hi,

Replace SPL with _SFR_IO_ADDR(SPL) and so on with any other I/O register
names in asm sources.  I tried to maintain compatibility with existing C
sources, but asm sources need changes.

If you want the same asm source to build with older tools, just add this
in your asm sources:

#ifndef _SFR_IO_ADDR
#define _SFR_IO_ADDR(x) x
#endif

#define _VECTOR(N) __vector_ ## N

Actually it's already defined in <avr/sfr_defs.h> but only for C programs.
Move it above the "#ifndef __ASSEMBLER__" and it should work fine...
(I'll fix it in avr-libc CVS later.)

All I can suggest is to get some old inexpensive P2/Celeron/K6-2 box
(but avoid the old Celerons without the L2 cache; GCC is large, so cache
size can make a big difference in speed) with 64 MiB (or better 128 MiB)
of RAM.  But don't throw away that old P100 - it's still a fine box for
use as a DSL router/firewall, or even a small server, for example...

Some bugs and some backwards compatibility issues, as you can see.
It's normal, remember that it's still a development version which is
being broken and fixed all the time ;)
