[avr-gcc-list] building avr-gcc from svn head?

[John Regehr]

Does anyone on the list use the latest gcc as a basis for avr-gcc?

If so, I'd appreciate any pointers on how to do it.  Following "the 
standard procedure" I get the error below.

Note that I don't need a 100% correct compiler, my student and I are 
simply interested in having a large set of compilers to play with since 
we're doing some comparative testing that is aimed at finding compiler 
bugs.  If there are IRA issues we can perhaps help find them.

Thanks,

John Regehr
