I have a question about the C preprocessor.  I have the following code
fragment, which fails to compile on my system (4.2BSD):

#define	GROUP(group,subgroup)	(((group) << 8) | (subgroup))

#if	GROUP(0,0)
#endif

The #if chokes for some reason.  Can anyone in comp.lang.c see my error?
If there is no error, is this a known bug of the 4.2BSD cpp?
