System: NetBSD ds20 1.5.1 NetBSD 1.5.1 (DS20) #2: Fri Jul 27 16:37:54 EST 2001 ada@ds20:/usr/src/sys/arch/alpha/compile/DS20 alpha


>Description:
The ## operator concatenates the symbols on either side.

In the cpp in 1.5.1, a##b evaluates to a##b rather than ab.  The C compiler
then handles this case as evaluating to ab.

The assembler does not understand this case, however.  Thus, one cannot use
the # and ## preprocessor operators in assembly language files.
