 Um, I guess you're assuming that you're using x86? As mentioned before a few
 times, 64-bit Linux ports run these programs fine, once you work around the
 32-bitisms in GAMESS. Actually, the new linker supports -taso, which is
 about all you need.

 So if you're using an x86, it shouldn't be that hard to build a Fortran I/O
 library that always uses the other calls, but then you still have to
 convince the library that the record sizes should be 8 bytes, not 4. That's
 a #define somewhere.
