On SCO OpenServer 5.0.7, sys/socket.h does not define either SHUT_RDWR, SHUT_RD, and SHUT_WR. This causes a problem when running `make test`.
May I suggest a patch similar to the following patch that improves the workarounds for missing SHUT_RD, SHUT_WR, and SHUT_RDWR definitions? $ cat curl-7.76.0-i686-pc-sco3.2v5.0.7-3.patch --- curl-7.76.0/lib/curl_setup.h.orig 2021-03-30 07:39:12.000000000 -0500 +++ curl-7.76.0/lib/curl_setup.h 2021-04-19 15:37:51.000000000 -0500 @@ -715,10 +715,12 @@ #endif /* - * Portable symbolic names for Winsock shutdown() mode flags. + * Portable symbolic names for Winsock shutdown() mode flags and other + * systems that do not define them. */ -#ifdef USE_WINSOCK +#if defined(USE_WINSOCK) || \ + !defined(SHUT_RD) && (defined(HAVE_SOCKET_H) || defined(HAVE_SYS_SOCKET_H)) # define SHUT_RD 0x00 # define SHUT_WR 0x01 # define SHUT_RDWR 0x02 Justification: $ grep shutdown /usr/include/sys/socket.h int shutdown __P((int, int)); On these systems, `man SSC shutdown` mentions use of -lsocket and documents the values to use when calling shutdown().
