Having successfully built recent versions of curl on a very old UNIX
(SCO OpenServer 5.0.7) for some time, it is disappointing to discover
that the latest official release I can build at this time is now 7.65.3.
Every build for releases after 7.65.3 fail with a message similar to:
$ make

make[1]: Entering directory '/csdi/src/sco507/curl/curl-7.66.0/lib'
make all-am

make: *** [Makefile:946: all-recursive] Error 1
A self-built gcc-3.4.6 is used vs. the vendor-supplied 2.95.3.
The configure statement used is consistent with what has worked
in the past:
CFLAGS="-static" \
./configure \
--disable-threaded-resolver --with-libssh2 \
--enable-shared --enable-static --prefix=${PKG_PRFX}
This is where the problem occurs:
#if defined(HAVE_SYS_UN_H) && defined(AF_UNIX)
case AF_UNIX:
if(salen > sizeof(sa_family_t)) {
su = (struct sockaddr_un*)sa;
msnprintf(addr, MAX_IPADR_LEN, "%s", su->sun_path);
}
else
addr[0] = 0; /* socket with no name */
*port = 0;
return TRUE;
#endif
In 2018, a patch for include/curl/system.h allowed building recent releases
on SCO OpenServer 5.0.7:
-#elif defined(__GNUC__)
+#elif defined(__GNUC__) && !defined(_SCO_DS)
...
#else
/* generic "safe guess" on old 32 bit style */
# define CURL_TYPEOF_CURL_OFF_T long
# define CURL_FORMAT_CURL_OFF_T "ld"
# define CURL_FORMAT_CURL_OFF_TU "lu"
# define CURL_SUFFIX_CURL_OFF_T L
# define CURL_SUFFIX_CURL_OFF_TU UL
# define CURL_TYPEOF_CURL_SOCKLEN_T int
#endif
Is there perhaps a generic, "safe guess" for this, or some idea on how
to start to break this down or avoid it altogether. It is unfortunate
that ./configure doesn't detect this.
Full make and ./configure output for 7.76.0 follows.

Oops!
Your 'rm' program seems unable to run without file operands specified
on the command line, even when the '-f' option is present. This is contrary
to the behaviour of most rm programs out there, and not conforming with
the upcoming POSIX standard: <http://austingroupbugs.net/view.php?id=542>
Please tell bug-automake_at_gnu.org about your system, including the value
of your $PATH and any error possibly output before this message. This
can help us improve future automake versions.
Configuration will proceed anyway, since you have set the
