charset="utf-8" From: Michael Tokarev This will stop linking softmmu-specific os_parse_cmd_args() into every qemu executable which happens to use other functions from os-posix.c, such as os_set_line_buffering() or os_setup_signal_handling(). Also, since there's no win32-specific options, *all* option parsing is now done in softmmu/vl.c:qemu_init(), which is easier to read without extra indirection, - all options are in the single function now. This effectively reverts commit 59a5264b99434.
