  Uh, well, I guess it would be possible. But I have some concerns:

  1. ppport.h is already too big. :-)

  2. There is code in ppport.h to actually remove an

       #include "ppport.h"

     if it appears not to be needed. If it's not needed in your
     included file, it might be dropped from there and moved to
     the other file that included the first one. This would make
     the logic much more complicated.

  3. As ppport.h is configurable, it's not (always) a good idea
     to put it into a file that's included from another file.

  I guess I'll have to think about this a little more. Maybe I can
  come up with a fancy solution that doesn't increase the code size
  too much.

  I don't think so. Because :
  1. your redefinition of SVt_PBVM is probably what most XS modules want
  2. anyway, if we remove it from the core, it might appear in Devel::PPPort :)

* have an --env option for soak to set env variable combinations

* only overwrite generated files if they actually changed

* try to make parts/apicheck.pl automatically find NEED_ #defines

* implement snprintf with newSVpvf for >= 5.004, which is safer?

* add support for my_vsnprintf?

* try to perform some core consistency checks:

  - check if 'd' flag in embed.fnc matches with
    supplied documentation

  - check if all public API is documented

* check (during make regen?) if MAX_PERL in PPPort_pm.PL
  needs to be updated

* see if we can implement sv_catpvf() for < 5.004

* MULTICALL ?

* improve apicheck (things like utf8_mg_pos_init() are
  not currently checked)

* more documentation, more tests

* Resolve dependencies in Makefile.PL and remind of
  running 'make regen'
