I think what has caused my problem is that I am using the JEE version of 
Eclipse that I have added the C/C++ project to, and the JEE version has 
project auto build active by default, which is the only way java 
development should be done (in my opinion) as when you get these sorts 
of statement errors for standard java processes one of the solutions 
provided is for Eclipse to add the necessary include file into the code 
to resolve the issue (admittedly this won't work for user defined 
processes). I can turn off the auto build functionality.

I may be approaching this process from the wrong angle, but from my 
perspective I ideally need to create a project containing all the 
modules that make up calc, so that when I change the source code I can 
compile it and then run unit tests on the pivot processes and system 
tests on the entire calc program to make sure I haven't adversely 
impacted anything else in the application, particularly if I can 
implement the menu entry to allow formatting of pivot variables post 
pivot table creation.
The easiest way to implement this is to create a project and then build 
the project which will then create the program.

The only other editor I use occasionally is Netbeans but it does the 
same thing.

I'll check these out and see if I can understand these first to try to 
work out how each of the modules interact with each other amalgamate to 
produce the entire calc application.
