I may be trying this yet tonight....  But I want to hack on trans/kbd.c
some more before I build again and it's late.  Maybe tomorrow.

Hmmm.  I checked a few with ldd and they are looking for libc.so.6
which doesn't look good.  These libs come with the gcc-i386-gnu package.
I have version 1.7-4 of this package installed - and it looks broken.
It worked last time I built gnumach, but maybe it doesn't need any of
the broken libs.  If I cannot build either, I'll report a bug against
gcc-i386-gnu.  And I may report one anyway if I can confirm it's really
broken and not just my tired imagination.

the right dir).  Ummm.  If the cross-compiler really is broken, don't
get your hopes up.  I'd expect it to try linking the same broken libs.

AFAIK, yes.  Also, MAKEDEV knows com[0-9] so this looks right.

BTW, these troubles only seem to come from cross-compiling.  I've done
a number of native builds without problem.  If that works for you,
there's a way to go....
