A typical error output:
CXX    target.o
/home/srs/DEBs/gdb/gdb-8.2/gdb/target.c: In function ‘int
dispose_inferior(inferior*, void*)’:
/home/srs/DEBs/gdb/gdb-8.2/gdb/target.c:2028:16: error: ‘thread’ was not
declared 
in this scope
   thread_info *thread = any_thread_of_inferior (inf);
                ^~~~~~
/home/srs/DEBs/gdb/gdb-8.2/gdb/target.c:2028:16: note: suggested alternative:
‘myread’
   thread_info *thread = any_thread_of_inferior (inf);
                ^~~~~~
                myread

Sorry, but the compiler directive is hidden from the output (by libtool??).

ii  gcc            4:8.2.0-2    hurd-i386    GNU C compiler
ii  g++            4:8.2.0-2    hurd-i386    GNU C++ compiler

I would be very happy if you could be consistent in the coding: Either use
struct thread_info everywhere or not.

Thanks!
