188 The --enable-gc2 options was replaced by --with-gc. Choose boehm for the
189 Boehm garbage collector. Also see README.boehm.
194 Now runs on some SGI systems, which are based on the mips architecture.

208 Finally moved the entire distribution to autoconf/automake. This should fix
209 some of our problems with supporting different compilers. Thread support and
210 the use of the new garbage collector can be enabled/disabled from using
213 --enable-threads [default]
216 --enable-gc2 [default]

227 Added unlimited stack for GC and main thread.
228 Some optimzations for instructions which operate on constants.
230 * Version 0.20 (released)

233 Hardware null pointer check added, fixed severe errors in GC/Threads, type
234 check and IEEE arithmetic.
236 * Version 0.20beta (can't remember)
237 =========================
239 There is a completely new JIT compiler which is about 7 times faster and
240 produces better code.
241 Multithreading is now supported.
242 A lot of bugs have been fixed.
244 * Version 0.10 (ancient history)
247 The initial version included the old JIT and support for lang, util and io.
