* dcrt0.cc: New global variable `ignore_case_with_glob'.

(dll_crt0_1): Disable case-insensitive globbing before calling `main'.
* environ.cc (glob_init): New static function to set or clear
`ignore_case_with_glob'.
(known): Changed "glob" entry to call `glob_init'.
* glob.c (match): Use case-insensitive globbing if needed.
