Subject: [PATCH] Remove a BSD-ism.
|
|
|
|
CTRL('L') is a BSD-ism. CTRL() is defined in sys/ttydefaults.h
|
|
which does not always exist. Instead of adding scons tests for
|
|
needing CTRL() and its include files just replace with a simple
|
|
constant.
|
|
|
|
Needed for musl and found by Baruch Siach <baruch@tkos.co.il>
