Despite being a great fan of David's work I feel
compelled to mention at this point that I posted
a program on the RDS page in June '98 called incbm.e,
which does exactly this.
A quick test run on "title1.gif" from the RDS page,
converted to .bmp format with PSP4 produced the
following results:
title1.bmp - 23.3k
title1.xpm - 22.7k
title1.e (incbm) - 10.1k
The simplicity of the test bitmap has been
kind to XPM; It more than doubled the size
of some I tried it with.
incbm.e is available from the utils section
of the archive on the RDS page under the heading
of "convert .bmp to .e" (it might trim down that
minesweeper game a bit 
I also have an updated
version that will save any euphoria object in this
format. I'll tidy it up and post it, if anyone's
interested.
