[MiNT] Binutils 2.18 + GCC 4.2.3

[MiKRO <miro.kropacek@gmail.com>]

Hi,

Today I finally found some time to compile super-optimized version of aranym on linux so I started the following -- I'm trying to compile 060-optimized gcc/binutils in one go, i.e. some kind of "super bootstrap" where gcc and binutils are 3-stage-bootstrapped against each other. It's officially supported, you just need to set up some links and that's it.

However, I found some new problems (using newest stuff from Vincent's site):

- native binutils2.18 patch isn't included in 13.01.2008 patch (forgotten?) -- that means that getopt() check and BASH_LINENO in ld/genscripts and libiberty bugs as well (EOF issue)

- for some strange reason, this:

produces bus error on 'ar' and absolutely nothing helps (make, bash, sh, install, this ar -- everything set to >=256K stack + TPA is 4 MB). What is interesting, when I copy/paste this into script (toswin2 buffer is too small), it creates libgcc.a without any problem..

- next thing, after some time, I'll get:

I don't know what exactly it means, I changed t-mint from m68020-60=m68060 to m68060=m68060 and added m68060 to multilib targets. Where comes that 68040 architecture, that's real mystery for me. But maybe it has something to the with CFLAGS I set in 'make'? (make CFLAGS='-O2 -m68060' but LIBCFLAGS I left without m68060)

Any clues? :)
