Can you explain what are the holes[].begin and holes[].end used for in
Sicstus Prolog?  The .bss section indeed begins at `edata' in v2, but
I'm not sure about the .end part (if it should give the end of .bss,
then you should use (char *)&end, I think).  And what about the two
other variables that reference `_go32_info_block'?  How are they used?

It's possible that the message you've found in the mail archives are
talking about DJGPP v1.x (the date of the message should tell), in
which case the solution might need some tweaking.  But unless somebody
has already done that and might therefore have an exact answer, you
will need to explain the use of these values in order to have a
solution.
