So when you go to redefine the key sequence in Eclipse to do ‘Build
All’ make sure you’re hitting the Ctrl key and not the Shift key. It
explained why I couldn’t define the CXXFLAGS macro in my Makefile.
Instead of Ctrl-X Ctrl-M for build all, I had accidentally defined it
as Shift-X Shift-M. Weird (that it let me), Cool (that I could do it),
but took me a little while to figure out that’s what it was and not
something wrong with my keyboard when Shift-X didn’t do anything
