Greetings,

The configure.ac file below, produces a configure script that fail to detect
sctp on Alpine linux (Linux localhost 6.1.75-0-virt).
The same configure script will correctly detect sctp on Arch linux (Linux
alarm 6.2.10-1-aarch64-ARCH).
I used autoconf from their package manager (2.71 and 2.72 respectively), but
the two resulting configure scripts, despite differences, produces the same
results on both machines. Always fail on Alpine, always correct on Arch
linux.

Best Wishes,
bengt

configure.ac:
AC_INIT
    AC_CHECK_HEADER(netinet/sctp.h,
        [LIBSCTP=libsctp.so.1
         AC_DEFINE(HAVE_SCTP_H, [1],
            [Define to 1 if you have the <netinet/sctp.h> header file])],
        [],
        [#if HAVE_SYS_SOCKET_H
         #include <sys/socket.h>
         #endif
        ])
AC_OUTPUT
