Missing def in screen.c

less/screen.c

Line 334 in 60050bd

#if ECHONL

unlike all other lines in this block, this line seems to have missed def in the #ifdef conditional and might cause some failures on some pre-processors like:

In file included from test.c:1:
test.c:20:5: error: missing binary operator before token "0x00000040"
   20 | #if ECHONL
      |     ^~~~~~
   ((tcflag_t)0x00000020)

Is there a reason why this is not an ifdef?

Per GNU, this is intended to be unsigned integer type https://www.gnu.org/software/libc/manual/html_node/Local-Modes.html
but any header that defines this with a cast will fail this evaluation as pre-processors don't understand C casting
