+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.

+/*
+ * Manuel Novoa III Dec 2000
+ *
+ * There were several problems with the qsort code contained in uClibc.
+ * It assumed sizeof(int) was 2 and sizeof(long) was 4. It then had three
+ * seperate quiicksort routines based on the width of the data passed: 2, 4,
+ * or anything else <= 128. If the width was > 128, it returned -1 (although
+ * qsort should not return a value) and did no sorting. On i386 with
+ * -Os -fomit-frame-pointer -ffunction-sections, the text segment of qsort.o
+ * was 1358 bytes, with an additional 4 bytes in bss.
+ *
+ * I decided to completely replace the existing code with a small
+ * implementation of a shell sort. It is a drop-in replacement for the
+ * standard qsort and, with the same gcc flags as above, the text segment
+ * size on i386 is only 183 bytes.
+ *
+ * Grabbed original file rg_ssort.c from snippets.org.
+ * Modified original code to avoid possible overflow in wgap calculation.
+ * Modified wgap calculation in loop and eliminated variables gap and wnel.

+ (aside from the initial '-') are option characters. If `getopt'
+ is called repeatedly, it returns successively each of the option characters
+ from each of the option elements.
+
+ If `getopt' finds another option character, it returns that character,
+ updating `optind' and `nextchar' so that the next call to `getopt' can
+ resume the scan with the following option character or ARGV-element.
+
+ If there are no more option characters, `getopt' returns `EOF'.
+ Then `optind' is the index in ARGV of the first ARGV-element
+ that is not an option. (The ARGV-elements have been permuted
+ so that those that are not options now come last.)
+
+ OPTSTRING is a string containing the legitimate option characters.
+ If an option character is seen that is not listed in OPTSTRING,
+ return '?' after printing an error message. If you set `opterr' to
+ zero, the error message is suppressed but we still return '?'.
+
+ If a char in OPTSTRING is followed by a colon, that means it wants an arg,
+ so the following text in the same ARGV-element, or the text of the following
+ ARGV-element, is returned in `optarg'. Two colons mean an option that
+ wants an optional arg; if there is text in the current ARGV-element,
+ it is returned in `optarg', otherwise `optarg' is set to zero.
+
+ If OPTSTRING starts with `-' or `+', it requests different methods of
+ handling the non-option ARGV-elements.
+ See the comments about RETURN_IN_ORDER and REQUIRE_ORDER, above.
+
+ Long-named options begin with `--' instead of `-'.
+ Their names may be abbreviated as long as the abbreviation is unique
+ or is an exact match for some defined option. If they have an
+ argument, it follows the option name in the same ARGV-element, separated
+ from the option name by a `=', or else the in next ARGV-element.
+ When `getopt' finds a long-named option, it returns 0 if that option's
+ `flag' field is nonzero, the value of the option's `val' field
+ if the `flag' field is zero.
+
+ The elements of ARGV aren't really const, because we permute them.
+ But we pretend they're const in the prototype to be compatible
+ with other systems.
+
+ LONGOPTS is a vector of `struct option' terminated by an
+ element containing a name which is zero.
+
+ LONGIND returns the index in LONGOPT of the long-named option found.
+ It is only valid when a long-named option has been found by the most
+ recent call.
+
+ If LONG_ONLY is nonzero, '-' as well as '--' can introduce
+ long-named options. */
