Update: there is IMHO no workaround possible. The problem is in DDEUtils
path handling. I can confirm that RISC OS Adjust has this problem fixed.
On the other hand, I feel this problem is more important than it is worth
so I've commented out the setting of DDEUtils_Prefix at the beginning
of each process if it is not defined (unixlib/source/unix.c). Program
builders are free to enable it when they are sure they won't be bitten
by this problem, i.e. the program is only run with fixed DDEUtils versions,
or the program is not using path variables either directly or indirectly.
