The only bug we probably need to fix is that the configure script doesn't include the required headers. This is a well-known situation with Xcode 12.

    initial v1  
    11Building Slrn 1.0.3 fails with this log message:
    22
     3{{{
    34:info:build /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_macports_release_tarballs_ports_news_slrn/slrn/work/slrn-1.0.3/src/misc.c:376:4: error: implicit declaration of function 'VA_COPY' is invalid in C99 [-Werror,-Wimplicit-function-declaration]
    45:info:build    VA_COPY(ap1, ap);
    56:info:build    ^
     7}}}

    79The reason seems to be that Slrn fails to build when it is configured as if the system has no support for `va_copy()`. However macOS Big Sur actually supports `va_copy()`. We seem to have two bugs here: one in Slrn itself for failing to build in this specific configuration and a further one in the configure script that fails to properly detect support for `va_copy()`.
    … …  
    911The reason for the latter problem is a bug in the configure script. The check uses `exit()` without properly including the necessary header file `stdlib.h` as indicated by configure in its config.log:
