odd lint errors

A recent message wondered why lint complains about a program
 #if UCB_NKB==1
 ...
 #endif
when the compiler handles it fine.  Actually the whole truth was not told.
The program was probably of the form
 #define UCB_NKB	1	/* mumble */
 etc.
with a comment.  Lint calls the preprocessor with the -C flag to
preserve comments (like /* VARARGS */).  Unfortunately cpp
preserves the comment in the #define but then fails to ignore it
while parsing the expression after #if.

We still have this too (someone found it just recently).  cpp's
author has been notified.
