[Frama-c-discuss] patchFile

What happens with the #include directives is entirely up to the pre-processor.
You can use whichever pre-processor you want,
or you can use the standard pre-processor
(Frama-C launches "gcc -C -E -I." by default) and make sure that the
include path
contains alternative versions of the files that Frama-C can handle.

Frama-C's front-end derives from CIL, which, I think, derives from FrontC.
Anyway, that part of the front-end is not supported in Frama-C. If you want to
apply a transformation to your C files, make a pre-processing command that
does what you want and use it with option -cpp-command.

The patch code was never supported, but the easier way mentioned above
works with all recent versions. You should still upgrade. The list of features
you are missing is at http://frama-c.com/Changelog.html (the latest, you are
missing if you are not a subscriber to "extended level" support
http://frama-c.com/support.html ).

The Nitrogen Open Source Frama-C version is packaged in Debian Testing
and numerous other Linux distributions, and a much-awaited Windows binary
is now available.
