-*************************************************************************
-**
-** This file contains low-level memory allocation drivers for when
-** SQLite will use the standard C-library malloc/realloc/free interface
-** to obtain the memory it needs.
-**
-** This file contains implementations of the low-level memory allocation
-** routines specified in the sqlite3_mem_methods object.  The content of
-** this file is only used if SQLITE_SYSTEM_MALLOC is defined.  The
-** SQLITE_SYSTEM_MALLOC macro is defined automatically if neither the
-** SQLITE_MEMDEBUG nor the SQLITE_WIN32_MALLOC macros are defined.  The
-** default configuration is to use memory allocation routines in this
-** file.
-**
-** C-preprocessor macro summary:
-**
-**    HAVE_MALLOC_USABLE_SIZE     The configure script sets this symbol if
-**                                the malloc_usable_size() interface exists
-**                                on the target platform.  Or, this symbol
-**                                can be set manually, if desired.
-**                                If an equivalent interface exists by
-**                                a different name, using a separate -D
-**                                option to rename it.
-**
-**    SQLITE_WITHOUT_ZONEMALLOC   Some older macs lack support for the zone
-**                                memory allocator.  Set this symbol to enable
-**                                building on older macs.
-**
-**    SQLITE_WITHOUT_MSIZE        Set this symbol to disable the use of
-**                                _msize() on windows systems.  This might
-**                                be necessary when compiling for Delphi,
-**                                for example.
