Environment: MIPS M/120 running Risc/os 5.00, using MIPS 3.0 compilers

This fixes a problem with encountered with the MIPS 3.0 C compiler.
The compiler treats the following two situations differently:

	#define bsd43_islower(c)	(.. c ..)
	#define islower			bsd43_islower
	#define ISLOWER			islower
	ISLOWER(c)

and

	#define bsd43_islower(c)	(.. c ..)
	#define islower		bsd43_islower
	#define ISLOWER(c)	islower(c)
	ISLOWER(c)

The first expands to
	bsd43_islower(c)
and the second expands to
	(.. c ..)

This looks to me like a bug in the C compiler, not the dd code, but the
work around is trivial.
