------- Additional Comments From dbaird at nmt dot edu 2004-12-22 07:13 ------- Just for the record, I am having the same problem. I am using GCC as the host compiler. My CHOST is x86_64-pc-linux-gnu.
I am building gcc-3.3.4 with patches from (Pre-Release 2.92): http://m68hc11.serveftp.org/m68hc1x-builder-2.92.tar.gz Compilation succeeds after I apply gcc-3.4.2-16925.patch from above.
