ead7252003-11-13Martin Stjernholm  the chosen Pike integer and float types, and various other basic macros. hashtable.c hashtable.h A simple hash table for pike strings. Used by cpp.c. pike_macros.h Miscellaneous support macros. pike_memory.c pike_memory.h The wrappers for malloc(3) etc and the dmalloc implementation.
