Well, that might be excessive.
I suspect the vast majority of the "#ifdef lint" are the copyright/version
strings:
#ifndef lint
static char const copyright[] =
"@(#) Copyright (c) 1989, 1993\n\
The Regents of the University of California. All rights reserved.\n";
#endif /* not lint */
And also, while I'll admit that various standards may think of "lint" as
a unreserved word in C language, various greps I've performed shows that
this is actually not the case: "lint" is very much an reserved word.
See our very own lint(1) for instance:
[...] The lint
utility runs the C preprocessor as its first phase, with the preprocessor
symbol ``lint'' defined to allow certain questionable code to be altered
or skipped by lint. Therefore, this symbol should be thought of as a
reserved word for all code that is to be checked by lint.
Considering the history of the "lint" symbol, I think we should
just declare ANSI and/or POSIX in error here and treat "lint" as
what it is: A well-defined reserved word.
I can personally live with any particular symbol we chose...
