octave 2.1.7 can't load example oregonator.oct

[Gary Holt]

Bug report for Octave 2.1.7 configured for %CANONICAL_HOST_TYPE%

Description:
-----------

First, there's a simple error in the mkoctfile script; at lines 106 and
109, there is an extra ;; which my bash shell doesn't like.

I've just picked up octave 2.1.7 and I've been completely unable to compile
any dynamically loaded modules.  When I attempt to access any function in
the .oct file, octave says that the symbol

   check_version(const string &, const string &)

is undefined.  (Well, actually, since string is a templatized type, it says
that check_version(const basic_string<....>, etc.) is undefined.)

I'm using the egcs (1.0.3a) compiler with pentium gcc optimizations on a
linux libc5 system.  (I have to use the egcs compiler because the extension
modules I need to compile won't work with the older gcc.  I was unable to
compile octave 2.0.9 with the egcs compiler.  If it's possible to do so,
I would be just as happy to use 2.0.x as 2.1.x.)

Repeat-By:
---------

  % mkoctfile oregonator.cc     # This is the oregonator.cc in the examples
                                # directory that comes with the octave
                                # distribution.
  % octave
  > oregonator
  
If I have built only static libraries (the default configuration option),
then this tells me that check_version(const string &, const string &) is
undefined.  If I configure with --enable-shared, it simply dumps core.

Fix:
---

  First, remove the extra ;;'s in mkoctfile.in and mkoctfile.

  I wish I knew how to get around the other problem.  Are dynamically
  loaded functions simply not working at all in this development
  release?  Can someone suggest a release that I should be using, which
  I can use the egcs compiler with?
