* ANSI suggests parenthesizing the identifier. This is a reasonable
* and legal approach, even for K&R C.
*
* A bug in the MIPS compiler used on MIPS, IRIS, and probably other
* MIPS R[23]000 based systems, causes the compiler to reject
* these declarations (at least at the current time, 1989 August).
* To avoid this bug, we conditionally define and use UNMACRO.
