Subject: bug#70716: flymake-cc creates `-.o` files
Date: Thu, 2 May 2024 15:10:18 +0200

[Message part 1 (text/plain, inline)]
`flymake-cc-use-special-make-target`, the standard value for `flymake-cc-command`, generates a command like

  make check-syntax CHK_SOURCES="-x c -c -"

which causes the compiler (at least Clang) to create the file `-.o` that is never cleaned up and whose name is mysterious and awkward to remove.

What about the patch below?
