Not so long ago I tried running NetBSD on one software emulator for 
these 68k processors :-) The idea was to have several emulated systems 
(68k, arm, etc), with which to port ECL, mostly as an exercise of 
stability and platform independence. Needless to say, I did not get very 
far away. Already compiling/installing the emulator was too much time.

I began building ECL on a NetBSD like a couple of hours ago. Last time 
it worked fine on NetBSD/x86 and NetBSD/Alpha.

Hmm, I have no problem changing the name in ecls/src/h/stacks.h, since 
it is only used there.

I'll see if I can reproduce this. The test for the --soft-float flag can 
be easily added to aclocal.m4

None of these problems show in the other ports. I wonder if the bignum 
library GMP is working there. Have you tried installing NetBSD's own GMP 
and compiling ECL against it?

All kind of help is welcome. It would be nice if ECL becomes the NetBSD 
of Common-Lisps :-)  ("A Common-Lisp that can run in your toaster" :-D)
