If the memory footprint was less than was needed for the linkage stage 
would this matter?

Obviously this isn't comparing "like with like", since the compiler 
footprint would presumably be per-unit rather than for the entire 
program. But any realistic development system has to be prepared to 
allocate enough memory for linkage, 512Mb is realistic for building e.g. 
Lazarus so it's reasonable to argue that that space is also available 
for compilation.
