Hi,

with source cvs'updated some minutes ago on MacOS:

> sw_vers 
ProductName:		macOS
ProductVersion:		15.1
BuildVersion:		24B83

using newest Developer-Tools updated yesterday:

*** Failed target:  ctags.lo



With the same source on NetBSD-amd86 this is only a "warning" and the compile succeeds:

     create  ctags/.depend
    compile  ctags/C.lo
    compile  ctags/ctags.lo
    compile  ctags/fortran.lo
    compile  ctags/lisp.lo
