Yes, the second solution looks like the right thing to do. May I add
another RFE here that somewhat relates to your proposal:
Right now an 'Extension' is basically a flat list of files, to which
some parameters are associated, specifying the build procedure.
I'v had to work with code (all belonging to the same 'extension
module'), where some files needed other compiler options than the
Would it be possible to allow 'Extensions' to be composed not only
of files, but of 'sub extensions' ? Each such 'sub extension' would
contain its own parameters (possibly inheriting default values from
their parent), and the final link stage would just combine all the
thusly generated .o files into one module.
That seems completely doable, and even fully backward compatible.
Of course, there, too, the order of execution may be important.
