Re: Mondoarchive appears to ignore requested tape blocksize

Digging further it would appear that this relates somewhat to a problem in
mr_popup_and_get_string() in newt-specific.c

Running under the debugger, I can see that typed value pointed to by
entry_value at line 770.  It seems the call to newtFormDestroy wipes out the
value I typed in.

I think this needs some looking at by the developers.  Please!!!!

Yuk!

Running a (slightly modfied) version of that code:

	
mr_asprintf(sz_size,"%ld",bkpinfo->internal_tape_block_size);
		tmp = mr_popup_and_get_string("Tape block size?", "What is
the block size of your tape streamer?", sz_size);
		if (tmp == NULL) {
			log_to_screen("User has chosen not to backup the
PC");
			finish(1);
		}
		bkpinfo->internal_tape_block_size = atol(tmp);
		mr_free(sz_size); sz_size=NULL; mr_free(tmp); tmp=NULL;
		
under gdb, shows that the compiler has chosen to optimise out the setting of
bkpinfo->internal_tape_block_size . 

It also appears to have optimised out the return value from
mr_popup_and_get_string so the char* value returned bears no relation to the
value that variable entry_value had at line 775 of newt-specfic.c.

Arrgghh!

Even with the corrected source I just submitted, mondoarchive appears to be
writing buffers of size 32768 (in the case in point I request a tape buffer
of 65536).
