The long check also fails with the Open Watcom compiler. Here's a snippet
from config.log for the code that should work:

| typedef char dummy_arr[sizeof(long) == 4 ? 1 : -1];
|
| int
| main ()
| {
|
| dummy_arr[1] = (long)1;
|
| ;
| return 0;
| }
|
configure:4809: owcc -c -fmath=387 -Wextra conftest.c >&5
Error: Compiler returned a bad status compiling 'conftest.c'
