| 31 | # MKncurses_def.sh -- generate fallback definitions for ncurses_cfg.h

| 35 | # Given the choice between constructs such as
|

| 36 | #
|
|---|
| 37 | # #if defined(foo) && foo
|
|---|
| 38 | # #if foo
|
|---|
| 39 | #
|
|---|
| 40 | # we chose the latter. It is guaranteed by the language standard, and there
|
|---|
| 41 | # appear to be no broken compilers that do not honor that detail. But some
|
|---|
| 42 | # people want to use gcc's -Wundef option (corresponding to one of the less
|
|---|
| 43 | # useful features in Watcom's compiler) to check for misspellings. So we
|
|---|
| 44 | # generate a set of fallback definitions to quiet the warnings without making
|
|---|
| 45 | # the code ugly.
