Many thanks for the idea, Lee.

I did "make -p", saved the output as a text file, and then grepped it for
"-c". The results were mostly "COMPILE.<something> = $(<something>)
blah-blah -c" as you suggested.

Given that all my Makefile is doing is printing a message and then
creating a directory, I can't see why these compile rules would be causing
issues. Nevertheless for kicks I defined all the <something>s about in my
Makefile like this:

CC = g++
FC = g++
PC = g++
CXX = g++

So the command should at least produce a different error to "File -c not
found". But the result of make was exactly the same as before.

Any other ideas, people?

Many thanks,

WPB
