#if bug in 'lint'
>From pur-ee!bruner@Berkeley Tue Sep 29 16:34:48 1981
I have also had problems with "#if" statements when running "lint".
The problem appears to be a vanilla 7 bug in the C preprocessor.

It appears that "cpp" does not properly handle comments within
conditionals.  For instance, in the following code

       #define JUNK 1 /* comment */
       #if JUNK == 1
       --blah--
       #endif

the "#if JUNK == 1" is expanded to "#if 1 /* comment */ == 1",
and the preprocessor apparently doesn't understand the embedded comment.
Comments are only saved if the "-C" flag is specified when calling
the preprocessor.  Since "cc" doesn't specify "-C" and "lint" does
(to be able to read its directives from the source), the problem only
shows up when "lint" is run.
