-This is a fast malloc implementation that I wrote several years ago.
-I later used it as the basis of GNU malloc. My version differs from
-the GNU version in that it does not support debugging hooks, and does
-not record statistics. Therefore it is slightly faster.
-
-In order to safely link programs using this malloc with a C library
-that provides a different malloc, you need to make sure that
-malloc(), free(), and realloc() are defined in a single object file.
-Otherwise when linking you might get a combination of this malloc()
-with the library's free(). The Makefile builds such an object file,
-alloc.o.
-
-If you are using this malloc as the allocator for a C library of your
-own, and are not linking with another C library, then you don't need
-alloc.o. If you are building a C library, you should also write a
-replacement for the file "morecore.c" that doesn't pollute the name
-space.
-
-The header file "malloc.h" in this directory is NOT intended to be a
-public header file; it is for internal use by malloc and its
-friends. Don't install malloc.h in a public include directory!
-
-When porting this allocator to a new machine or operating system, you
-should inspect the definition of BLOCKSIZE in malloc.h to make sure
-it is greater than or equal to your target machine's virtual memory
-page size; otherwise valloc() won't work properly. (If you don't
-care about valloc() then BLOCKSIZE doesn't matter.)
-
-You will also need to provide a machine-dependent _default_morecore()
-function; see morecore.c for a sample version that works on Unix.
-Your morecore function should return a pointer to a newly allocated
-region of the given size, aligned on the most pessimistic alignment
-boundary for the machine. Subsequent calls to morecore should return
-contiguous memory, and calls to morecore with a negative argument
-should return memory to the system. If no memory is available
-morecore should return NULL.

-Bug reports to Mike Haertel, mike@cs.uoregon.edu.
-This version is dated March 26, 1993; include this
-date with your bug report.
