[svn r135] * Merged DMD 1.025 * * Fixed a minor linking order mishap * * Added an command line option -annotate * * Fixed some problems with running optimizations * * Added std.stdio and dependencies to lphobos (still not 100% working, but compiles and links) * * Fixed problems with passing aggregate types to variadic functions * * Added initial code towards full GC support, currently based on malloc and friends, not all the runtime calls the GC yet for memory * * Fixed problems with resolving nested function context pointers for some heavily nested cases * * Redid function argument passing + other minor code cleanups, still lots to do on this end... *
