[svn r219] Fixed: the tango/lib/gc/basic garbage collector now compiles and links into an executable (change in tango/lib/llvmdc-posix.mak), closes #5 . Changed: removed the crappy realloc based dynamic memory runtime and started moving over to DMD style runtime support, part of moving to real GC. Fixed: dynamic arrays now use GC runtime for allocating memory. Fixed: new expression now use GC for allocating memory. Changed: revamped the dynamic array support routines related to dynamic memory. Fixed: assertions no longer create exsessive allocas. Changed: misc. minor cleanups.
