I don't see any file called br1.c there. It does need to be generated. Or do
you mean a different thing?

No. Only with Cygnus. Then we have a bash, too.

See above.

I have the newest version.

I did get this yesterday, when I tried to compile for Solaris. Aha, that's
why. (Btw, there are problems, too. But this is a different story.)

configure doesn't work for me. I've tried to make up somthing by myself from
the generated Makefile on Solaris. But I've given up. It's way up over my
head. Sorry for your effort.

I can't even build makebearoff or makebearoff1. I don't get over quite some
undefined references.

Thank you,
