+Causes \f(CW<name>\fP to be defined as a macro.
+The first form is equivalent to `\f(CW-D<name>=1\fP'.

+in front of all the source files.
+.in
+.LP
+\f(CW-U<name>\fP
+.br
+.in 5
+Acts as if the line `\f(CW#undef <name>\fP' is put in front of all
+the source files.
+.in
+.LP
+\f(CW-I<directory>\fP
+.br
+.in 5
+This puts \f(CW<directory>\fP in the include directory
+list.
+.in
+.LP
+\f(CW-R\fP
+.br
+.in 5

+.I lint
+checks the program according to the Reference Manual, because this

+of writing portable programs.
+With this flag on, some constructs, otherwise not allowed, are

+.in
+.LP
+\f(CW-l<name>
+.br
+-llib-l<name>.ln

+.in 5
+`\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'.
