Another message suggests to configure GCC with the following
configure option:
--with-gc=3Dsimple=20
http://sources.redhat.com/ml/cygwin/2000-11/msg01094.html
Maybe Gunnar could try out to compile avr-gcc using the above=20
option.

From time to time I test avr-gcc with gcc.c-torture/execute/*.c it's
about 300 tests.
I'm planning to test avr-gcc on this week or on next week.

From Spain hello and welcome, Barry.
I'm working with Atmel microcontrollers only few months ago.
I'm starting developing a system based in Atmega163 to send alarms through
GSM modem.
I'd say much more but my English is very bad, so I say:
"El ambiente es bueno, y hay gente que ademas de generosa sabe un huevo".

From my experience, using only -g and not using -O? is what you should do
when you have to go into debugger. Besides, in the debugger, optimizing
your program is a moot point.

:)Apologies if this seems a little off-topic. I am currently experiencing

:)Running with -O0 does of course help a little but certainly does not fix
:)the problem entirely.
:)
:)We are not talking about minor errors either. Quite often, GDB will say

:)Even some help determining if the fault lies in GCC/G++ producing the

:)(avr-objdump isn't really appropriate for this as it may contain the

From the languege reference i know the shift operator to use like value<<=
1=20
but not the other way around.
