Package: cproto
Version: 4.7x-1
Severity: normal

Dear Maintainer,

I'm trying to work around some explosive source code (src:tgif 1:4.2.5-2)
with something like
  cproto -E 'cpp' -D'ARGS_DECL(...)=__VA_ARGS__' -{P,F,C}"int f(a, b)" -a exec.c

Quoth cproto(1):
  -E cpp Pipe the input files through the specified C preprocessor command 
         when generating prototypes.  By default, the program uses /lib/cpp.
  -E 0   Do not run the C preprocessor.

This doesn't appear to hold at all. /lib/cpp isn't a valid preprocessor,
but even supplying -E cpp or -E /bin/cpp I see no preprocessing happen
(and don't see an execve() in strace at all).

It looks like -E working at all is guarded on #ifdef CPP?
It would be nice, for future readers, to say "-E ... ignored",
if this is intended.

Best,
