I did this

Built curl for MS-DOS in CI, where the build reaches this line due to SIZEOF_OFF_T <= SIZEOF_SIZE_T (4 <= 4):

lib/ws.c: In function 'ws_payload_remain':
lib/ws.c:658:35: error: comparison is always false due to limited range of data type [-Werror=type-limits]
  658 |   if((curl_off_t)payload_buffered < 0)
      |                                   ^

I expected the following

Clean build.

curl/libcurl version

master

operating system

MS-DOS (maybe others with SIZEOF_OFF_T <= SIZEOF_SIZE_T)
