New build system in "master" branch

After 10+ years of fighting recursive make, I've committed a new system. It's only used if you want, by editing Make.inc, and adding a line: BOILER=yes When you do that, the build should be MUCH faster. Everything goes into a "build" directory, so don't look for libs/binaries in their usual places. On my system, the build is rather a lot faster. Anyone doing even occasional development should look into using it. Let me know what you think. Alan DeKok.
