20000428: bug fix for SGI progs reading Linux written gem files

Pete,

I run on an SGI and read our grid files that are written from a Solaris x86
machine (whiuch will define the same MTMACH and byte order as Linux)
and have not seen your troubles- So we should probably make sure we are
comparing apples here and see what SGI OS and compilers you have.

I am running IRIX64 with:
--> uname -R
6.5 6.5.7m


--> showprods
I  c_dev                09/29/1998  C Headers and Libraries, 7.2.1
I  compiler_eoe         03/07/2000  IRIX Standard Execution Environment (Base
                                    Compiler Headers and Libraries, 7.2.1.3m)
I  ftn77_dev            09/29/1998  Fortran 77 Headers and Libraries, 7.2.1

The Makeinc.irix file defines -o32 in the compilation flags, just to
be sure you still have that defined too.
