**
**	Use IRIX64 instead of IRIX for 64-bit IRIX (6.0).
**	Use IRIX5 instead of IRIX for IRIX 5.x.
**
**	This version tries to be adaptive using _MIPS_SIM:
**		_MIPS_SIM == _ABIO32 (= 1)    Abi: -32 on IRIX 6.2
**		_MIPS_SIM == _ABIN32 (= 2)    Abi: -n32 on IRIX 6.2
**		_MIPS_SIM == _ABI64  (= 3)    Abi: -64 on IRIX 6.2
**
**		_MIPS_SIM is 1 also on IRIX 5.3
**
**	IRIX64 changes from Mark R. Levinson <[e-mail]>.
**	IRIX5 changes from Kari E. Hurtta <[e-mail]>.
**	Adaptive changes from Kari E. Hurtta <[e-mail]>.
