[Tinycc-devel] [patch] implement the -M option

[Luigi Rizzo]

Hi,
attached is a very small patch for tcc that implements the -M option
(used to generate header dependencies by mkdep).
The patch is trivial -- essentially it reuses the code for -E to create
the list of headers used by a file.

The same patch also includes 4 lines that serve
to ignore the '-std=XXX' option sometimes used to invoke the compilers
(for what matters, my goal is try and build FreeBSD using tcc).
Feel free to put this in an #ifdef if you think is questionable.

Hope people will find it useful.

        cheers
