I won't be able to test your patch so here are just a few remarks.

Did you compile Guile with optimizations?  When using GCC, compiling
with `-O0' quickly yields stack overflows (to that point that one
doesn't even get to the REPL).

Sorry, I don't understand this.

I don't known.  We should normally not have to touch the `#ifdef's
around `alloca ()' since they are the documented way to deal with
`alloca ()' [0].  OTOH, the `#ifdef's changed a bit in the Autoconf
manual (see [0]), so perhaps we should update them accordingly.  Would
this solve your problem?

Otherwise, you can provide specific details as to why this arrangement
fails on your platform and report it to the Autoconf maintainers.  :-)

In any case, I'd be surprised that it fails on Solaris 10 since this is
quite a widespread platform.

Also, when submitting a patch, please follow the GNU coding standard for
ChangeLog entries and code (see below).

Is there something wrong with the original form?

This should really be something like:

  static void
  startup ()
  {
    ...
  }

`scm_init_guile ()' is documented and perfectly legal in 1.8.0.  Is
there any reason why you removed it from test cases?

Thanks,
Ludovic.
