Subject: Add support for building with Tiny C for MS-Windows

* src/config.h.W32.template (HAVE_DIRECT_H, HAVE_STRCASECMP)
(HAVE_STRNCASECMP, HAVE_UMASK): Add __TINYC__ to MinGW condition.
(BATCH_MODE_ONLY_SHELL): Make this the default for Tiny C.

* build_w32.bat: Support building with Tiny C's tcc compiler.
