.I lint
|

checks the program according to the Reference Manual, because this
|
|
gives a definition of the language with which there is a better chance
|
|
of writing portable programs.

With this flag on, some constructs, otherwise not allowed, are
|
|
accepted.

`\f(CW-l<name>\fP' tells
|
|
.I lint
|
|
to search the lint library
|
|
\f(CWllib-l<name>.ln\fP for missing
|
|
definitions of functions and variables.
|
|
The option `\f(CW-llib-l<name>.ln\fP' makes
|
|
.I lint
|
|
search the lint library file \f(CWllib-l<name>.ln\fP in the current
|
|
directory for missing definitions.
|
|
Default is `\f(CW-lc\fP'; this default can be suppressed by
|
|
`\f(CW-l\fP'.
