     I am trying to run test-compat version 2.0.20.beta
on a MIPS Origin 2000 (mixed R10K and R12K) processors, 
under IRIX 5.5 and MIPSPro 7.2.1 compilers, no readline.
The compiler flags include -64, for 64-bit longs and 64-bit pointers
but 32-bit integers.  Whether I use -O3 (optimizer) or -g (debugger)
I get a discrepancy (in both static and dynamic modes).  See below.

    The first significant discrepancy is the signs of some 
elements in the vector beginning [4, 3, -1, 2, 3, 1, -11, 1, 7
Later, in the makebigbnf(sbnf) output, one output has
1.246346989334819161 and the other adds pi*I to this.

    I got additional discrepancies when I used -IPA (interprocedural
optimizations).  I assume these are compiler bugs.  
However I did run 2.0.11.beta in 1998 using the same compilers and
a -IPA flag.
