Write all C flags into `file.txt`, one flag per line.
If `file.txt` is `-`, then write the flags to stdout, one flag per line.
-no-rsp
By default, V passes all C compiler options to the backend C compiler
in so called "response files" (https://gcc.gnu.org/wiki/Response_Files).
This works in most cases, since it works around command line length
limitations on older systems (and windows), but some C compilers
(older versions of tcc for example) do not support them at all. When
you use -no-rsp, V will pass the C compiler options directly to the C
compiler, on the command line, without writing an .rsp file first.
-assert aborts
Call abort() after an assertion failure. Debuggers usually
install signal handlers for SIGABRT, so your program will stop and you
