Do you by chance have an alternate suggestion? Really the only part of my 
code that needs this functionality is the filesystem (and my JPEG codec). 
There must be a mechanism for accomplishing what I need.

I did try a "composite build" wherein my code was compiled with packed 
structures and eCos was compiled with aligned structures, and it DID work, 
but that's probably because I'm not using any OS functionality at all.
