We should be able to compile this without the need for an extender. Unless someone wants to write a BASIC program that breaks the 640K barrier there is no point in it. Right now it compiles to about 360K (1 floppy =-O) which still leaves plenty of room for a large program. I tried to compile with BC2 and it complained of running out of symbol space. This likely can be resolved by reverting to a normal compile that builds each .C file into an .O file. Then link them together. Looks like that was the way it had been done. Returning to that method will also improve re-build times for devs, especially those like me compiling on Linux. I can use a multi-threaded compile! _ZOOOooom_ 8-)
