Even better.

I've pushed the changes now. Hopefully did not mess anything up ;)

I have briefly went through the changes (quite a lot of them...):

1. I guess you could have separated those __HAVE_68881__ and whitespace /
syntax (ori #1 -> bset, movl -> move.l etc) / register (e.g. where you
decided that "a0" should be replaced with "a1" to better fit the fast call
code later) changes to make it a bit smaller for the final fast call patch.

2. "make WITH_DEBUG_LIB=yes WITH_PROFILE_LIB=yes' produces quite an odd
tree in "build/m68000": there are empty directories like "argp", "common"
etc from the source tree plus *.o and *.a files while in other "build"
directories there are just *.o and *.a files.

3. zic (and others) doesn't seem to be built for other than 68000:

(after all the targets are built...)

and that's it, the build is finished. "zic", "zdump" etc are located in
"tz" (source) directory and not in "build".

4. Is there a reason to build the debug targets on ELF by default?

5. I compared libc.a from commit 0a659908 (ICE workaround) and head

The good news is that majority of the code is exactly the same, most of the
changes is a different address for given module. However one thing seemed
odd, in function _eval_expr_val:

old code:

what are those .short 0xXXXX statements in .LC1 ? That's -m68000, there
shouldn't be any unknown instruction involved. Perhaps it is not code at
all but I find it odd that it differs (again, both are -m68000, same
compiler, same flags).
