Robert,

>I will get it and rebuild it.

I just stuck the object module out there in unix/760/fortran/SC5.0.

>It does suck, especially after we paid $395 for the compilers.

Exactly!  This will be the third problem that I have found in Sun Fortran
compilers.

The code is different.

I had the exact same observation.

>Our

Wow!  Twice as long!!  We don't see this kind of time increase here
at Unidata.

While we are chatting about machines, let me tell you what I did on the
machine I use at home:

The machine is one that I put together from parts:

FIC VA503+ motherboard:  $70
Intel Pentium 200 Mhz:   $200   (purchased some time ago, that is why it was
                                 so expensive; I was overclocking to 233 Mhz)
128 MB SDRAM             $140   (I just saw 2x64 MB PC 100 RAM for $39.99!)
PCI 2 MB video:          ???    (old)
40x CDROM                $40
rest in old system

I bought a 400 Mhz AMD K6-2 for $43 and an Intel 740 based 2X AGP video
card with 8 MB of RAM for $39.  A couple of weeks ago I got a 56 K ISA
modem for $42.50.

I put the modem and processor in my machine and changed a couple of
motherboard jumpers and rebooted.  I now have a fast 400 Mhz machine
that can access data though the modem nicely.  The build time for
McIDAS-X, -XCD (current release) on RedHat 5.2 Linux dropped from 46:40
to 27:20.

I got pretty excited about how cheap parts are getting, so I sat down
with Sunday paper adds (e.g. COMPUSA, BestBuy, pricewatch.com) and
priced out boxes based on AMD K6-2 processors.  I figure that I can put
together a 400 Mhz machine (no monitor) for about $425.  Pretty cheap!

I just thought that you would be interested...
