[En-Nut-Discussion] Need some installation help

[Daniel]

Hi again,
Well, its a bug in GCC-4.1.  Long switch statements cause an error to be 
thrown.  One solution is to split up the long switch statement in 
ethernut-4.2.1/dev/usart.c.  This problem shows up in both the Debian 
and Windows installation.  There is also a bug report filed about this 
problem:
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=31786

I'm new to ethernut by the way, got a little frustrated with the 
constant *** Error messages. 
Lesson learned: Google more, angry less.

Hope this helps someone else.
Cheers,
Daniel
