backend: There is no need for 'compiler-specific escaping' anymore Now that all command-line escaping for ninja is dealt with in the ninja backend, escape_extra_args() shouldn't need to do anything. But tests of existing behaviour rely on all backslashes in defines being C escaped: This means that Windows-style paths including backslashes can be safely used, but makes it impossible to have a define containing a C escape.
