Comment:

 Looks like there are many errors in the log of this form:

 {{{
 src/xwin.c:8709:4: error: implicit declaration of function 'plinz_'
 [-Werror,-Wimplicit-function-declaration]
    plinz_(isel,istat,
    ^
 }}}

 Implicit function declaration errors are a new problem we're having to
 contend with since the introduction of Xcode 12. Prior to that, this was
 only considered a warning. We should fix these problems, but until we do,
 you can avoid them by downgrading to Xcode 11 and/or the Xcode 11 version
 of the command line tools.
