2.0.1 Add work-arounds for kernel and library bugs under HP-UX. HP has been notified and will repair these soon. 2.0.2 Add support for DEC Alpha. Add %a pattern for printing addresses, which assumes they are passed in a void *. 2.0.3 30-Sep-1993 When realloc is passed a zero address, it should work the same way as malloc(). Fix forward declaration of mprotect() in page.c to use void *, not caddr_t, for addresses. IRIX 5.0.1 complained about that. 2.0.4 29-May-1994 Don't attempt to allow access to a zero-sized page when EF_ALLOW_MALLOC_0 is set. Attempt to un-map memory from Page_Delete(). If that doesn't work, fall back by protecting the page from all references. Un-mapping small segments of a mapping used to crash my SGI IRIX 5.0 system. I assume that nobody is running 5.0 any longer. 2.0.5 20-January-1995 Port to Linux.
