Hi,
I just completed a package for reading and writing dbf files, that I will
post soon so i will definately be affected since I used mostly the c
api. Would the option below mean that there would be macros defined in say
R.internals to have old style behave as new style, or would it be prefered
that maintainers write seperate routines for new and old versions. I am
imagining quite a bit of code bloat.
