[Nick Glencross]

I'll fix these (and some other things mentioned in other posts in this 
thread), and repost again in the next day or so,

Thanks all,

Nick

for fun I've written md5sum using IMCC, and have attached my first cut.
   

Yet another f'up. Some enhancements and nit picks.

- buffer should be a IntvalArray (or IntList still)
 (I've copied the splice over to intlist.c)
- extracting the chars out of the string can use this opcode:

    #$S0 = str[$I5]
    substr_r $S0, str, $I5, 1
 which reuses $S0

Both give a considerable performance improvement.

- getting argv is better written as:

 .sub _main
    .param pmc args
