--- Comment #14 from Eli Zaretskii <eliz at gnu dot org> --- And one more comment: using pre-quoted shell command (as opposed to just the preprocessor file name) in --preprocessor will not work with --use-temp-file, because the code in `run_cmd` breaks the command into argv[] array, and will treat the quoted string ("gcc -E ....") as a file name to invoke. This trick only works in the default pipe mode, because then the command is not broken into argv[] elements. So I really think this trick should not be supported, definitely not when it invalidates correct usage. -- You are receiving this mail because: You are on the CC list for the bug.
