   It does more than that: the C run-time library has code to transpose c and h 
directory names, so that this is done uniformly for all clients. By default, is 
is only done for ".c", ".h" and ".s". (This is how the compiler knows to open 
"h.fred" when you write "#include "fred.h"" in your C file.)

   When AMU sees a .SUFFIXES line, it adds the suffixes it sees to that list, 
using the C library call provided for that purpose. So, within AMU at least, 
the behaviour should be right. This was all done so that UNIX makefiles would 
work on Acorn systems without needing enormous amounts of work, and that's 
exactly what we are trying to do here.

   The above should all work providing that C files are referred to 
consistently within the makefile as "xxx.c", headers as "xxx.h", and SWI files 
as "xxx.swi". My guess is that there is a culprit "swi.xxx" somewhere. This 
will work fine on the Acorn machine, but fail under UNIX. In the form 
"xxx.swi", it should work the same under both.

   Is that the case? Also, maybe there are dynamic dependencies present in the 
makefile, having the same effect?

   (I hope you mean Territory.swi in a UNIX environment?)

   I can't see this repository yet---I'll have another go soon.
