I moved just dict_minimum.inc.  It gave me an end address of 0x3f00, so
I'm only wasting 256 words.  dict_minimum was intended to be in low
memory.  The amforth User's Manual says, "This file was called
dict_low.inc in previous versions of amforth. ....  The words included
in dict_minimum.inc are stored in the target system in low flash
memory."

Maybe you moved too much to low memory.  In the User's Guide it says you
should be careful.

The amount of high flash memory varies based on the type of AVR device.
Some small devices may
have so little high flash memory that you won't be able to fit all of
the words in this file [dict_core.inc] into the
available memory. Should this happen, you may be able to move some of
the .include statements from
this file into dict_minimum.inc (see below). Note, however, that this
must be done carefully, to keep
the flash read/write words (at least) in high flash memory.
