Some project files (iPhone) and backend files (Symbian) still reference m4.dat,
but I know not enough on how to remove that without breaking something.
Formerly create_project incorrectly assumed that a given object file is only
present once in an module.mk file. This is not the case for backends/module.mk
for example. There the Windows FS object files are in two different if blocks.
In this particular case it resulted in the object file being added to both the
include list and the exclude list.
Now the module.mk handler prefers files being in the include list.
Variadic macros are C99 and ugly in C++. If we would want to do it differently
we should rather rely on C++0x's initializer lists. But since we cannot assume
all compilers we want create_project to build support that we cannot do that.
User-visible output and project-specific names are now defined in a config header.
This allows an easier usage of the create_project tools in other scummvm-derived projects (such as residual).
