#63307: rsync-lart @2.6.6: error: array type 'va_list' (aka '__builtin_va_list') is
not assignable

     Type:  defect       |     Status:  new
 Priority:  Normal       |  Milestone:
Component:  ports        |    Version:  2.7.1
 Keywords:               |       Port:  rsync-lart
-------------------------+------------------------
 There's a few errors when building it, but this is the first of them:
 {{{
 lib/snprintf.c:220:2: error: array type 'va_list' (aka
 '__builtin_va_list') is not assignable
         VA_COPY(args, args_in);
         ^~~~~~~~~~~~~~~~~~~~~~
 lib/snprintf.c:155:35: note: expanded from macro 'VA_COPY'
 #define VA_COPY(dest, src) (dest) = (src)
                            ~~~~~~ ^
 1 error generated.
 gnumake: *** [lib/snprintf.o] Error 1
 gnumake: *** Waiting for unfinished jobs....
 }}}
 Note that there were some `-Werror=implicit-function-declaration` issues
 reported in `config.log`, so, since one of them was for `snprintf`, fixing
 that might mean it'd be possible to avoid even trying to build the buggy
 source file:
 {{{

 I'll attach the full logs next. Also ISTR rsync-lart conflicting with the
 main rsync port, too, last time I was able to get it to build, so it might
 be worth looking into that, too, once this is fixed.
