Hi all,

I have everything working with Solaris x86/Sparc and Studio 12 compilers, my only exception is wavread will fail, which I'm currently looking at. I believed I have
the problem figured out but need to code around it.

At this point, I can turn everything in, with the caveat on the read problem.

What is the advice of the group? And if folks want me to turn the work back in,
what is the best way to proceed with that?

Jim

I doubt that this is a bug in Octave.  It looks similar to the Cygwin
GCC bug discussed here:
