JG		 21 ECOFF symbol tables to the internal (usual struct) representation.
22 On a machine with the same byte-order and the same basic type
23 sizes and alignments as a MIPS machine, this is a no-op.
24 If the symbol TEST is defined when this file is compiled, a comparison
25 is made to ensure that, in fact, the output is bit-for-bit the same as
26 the input. Of course, this symbol should only be defined when
27 deliberately testing the code on a machine with the proper byte sex
28 and such. */
