I've now cleaned up that patch, and simply rebasing yours on top
shows what I meant:

 src/gdb/exec.c:184:59: error: could not convert ‘flags’ from
‘symfile_add_flags {aka enum_flags<symfile_add_flag>}’ to
‘objfile_flags {aka enum_flags<objfile_flag>}’
     symbol_file_add_main_1 (exec_file_host, from_tty, flags);
                                                           ^
 Makefile:1138: recipe for target 'exec.o' failed

I.e., the existing flags parameter to symbol_file_add_main_1
is _not_ a symfile_add_flags.  We can't just use it as is.

So yes, I think so.  I was just doing that here, this minute.
But I was replacing the from_tty parameter symbol_file_add_main
with a symfile_add_flags instead.  Let me do that and send
both patches.
