The interactive mode uses large several tables of options which can be configured. However, much of the contents of these tables are repetetive. For example, no struct is larger than half a kilobyte, so the offset only takes up 9 bits. Similarly, the size is only ever 4 or 8, and printhex is a boolean. Reduce the size of these fields. This reduces the size of the options tables by around 10 KiB. However, the largest contributor to the size of the options tables is the use of a pointer for the strings. A better approach would be to use a separate array of strings, and store an integer index in the options tables. However, this would require a large re-architecting of this file.
