/* Usage Notes:
*
* this module, and the misc/win32/utf8.c modules must be
* compiled APR_EXPORT_STATIC and linked to an application with
* the /entry:wmainCRTStartup flag. This module becomes the true
* wmain entry point, and passes utf-8 reformatted argv and env
* arrays to the application's main function.
*
* This module is only compatible with Unicode-only executables.
* Mixed (Win9x backwards compatible) binaries should refer instead
* to the apr_startup.c module.
*
* _dbg_malloc/realloc is used in place of the usual API, in order
* to convince the MSVCRT that they created these entities. If we
* do not create them as _CRT_BLOCK entities, the crt will fault
* on an assert. We are not worrying about the crt's locks here,
* since we are single threaded [so far].
