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