** SQLITE_SYSTEM_MALLOC // Use normal system malloc()
** SQLITE_WIN32_MALLOC // Use Win32 native heap API
** SQLITE_MEMDEBUG // Debugging version of system malloc()
**
** On Windows, if the SQLITE_WIN32_MALLOC_VALIDATE macro is defined and the
** assert() macro is enabled, each call into the Win32 native heap subsystem
** will cause HeapValidate to be called. If heap validation should fail, an
** assertion will be triggered.

** pared it down to just these two.)
**
** If none of the above are defined, then set SQLITE_SYSTEM_MALLOC as
** the default.
