I just did a search of the whole of src. It's *used* about a dozen
times across 5 otherwise unrelated .cpp files, but is only defined
here. Just to be certain, I did a make clean before trying this
again, and it's definitely saying multiple defs
e.g
/usr/bin/ld:
CMakeFiles/yoshimi.dir/UI/WidgetMWSlider.cpp.o:(.rodata+0x0):
multiple definition of `ADD_COLOUR';
CMakeFiles/yoshimi.dir/Interface/InterChange.cpp.o:(.rodata+0x1840):
first defined here
This happens at the linker stage.
Also, I thought the whole idea of putting things like this in a
#ifndef/#def block was to ensure it was only set once.
It is only set once *per file* which includes the header. But since the
symbol is extern, the linker sees one public copy per file, which
conflict with each other.
