Control: retitle -1 cproto: implies it runs /lib/cpp(?), actually runs gcc -E by default Control: tags -1 + upstream
Okay, nevermind that, apparently the preprocessor only runs without -a; however:
$ strace -fe execve cproto -D'ARGS_DECL(...)=__VA_ARGS__' -{P,F,C}"int f(a,
b)" exec.c
execve("/bin/cproto", ["cproto", "-DARGS_DECL(...)=__VA_ARGS__", "-Pint f(a,
b)", "-Fint f(a, b)", "-Cint f(a, b)", "exec.c"], 0x7fff563a9f98 /* 32 vars */)
= 0
strace: Process 3089145 attached
[pid 3089145] execve("/bin/sh", ["sh", "-c", "gcc -E
-DARGS_DECL(...)=__VA_ARG"...], 0x7ffd5d411a90 /* 32 vars */) = 0
/* exec.c */
sh: 1: Syntax error: "(" unexpected

so, it runs gcc -E.
One'd certainly think it ought run "${CC-cc} -E", but whatever.
It's definitely not running /lib/cpp!
