Hello,
I'm trying to compile SeaBIOS under NetBSD 5.1.2, that comes with gcc 4.1.3, and I'm getting the following error (I'm pasting the whole build log, since it's not really long, and may help in debugging):

This error only happens when compiling with gcc 4.1.3, with gcc 4.5.3 (under NetBSD also) the build process is successful. Since I guess it's a compiler problem, is there anyway I can workaround this issue?
Thanks, Roger.
