Yes, but it's the debugging evaluator, ie. when you run with --debug
so you can see scheme-level backtraces.

I'd have thought mingw is supposed to provide alloca.h or something to
give that function.  It's Gnu C so it must exist, as __builtin_alloca
or whatever I suppose.

I think so.  If the ioctl constant FIONREAD exists then the ioctl
function exists ...

Thanks.  I'll conditionalize it on ioctl existing too.

I see there's a select() in winsock.h, not sure if that's what should
be used in that bit of code ... maybe not.  I thought DOS did have a
way to ask if there was input waiting on an fd though.

Probably not unless mingw is providing it somehow.

I see boot-9 loads session.scm which loads documentation.scm which
uses regexps.  Bit annoying that.  I guess nobody's built anywhere
without regexps for a while.  It might work to remove the session line
from boot-9

    (module-use! guile-user-module (resolve-interface '(ice-9 session)))

You might be able to delete most of the guts of documentation.scm, it
shouldn't get used unless you run `help' or `procedure-documentation'
or whatever.

We can make arrangments to link to some good third party bits.

Yes, for all the library parts.  Test programs and example programs
I'm not so sure, but the bits you need to link into an executable are
supposed to be LGPL.

Dunno what 6 means.  I assume the exit status is low on the list of
priorities just yet though :-).
