You can also create src/Makevars by hand...   BTW it wants a capital M on OS
with case-sensitive file systems.

"Nothing else here" -- R CMD check should stop complaining if you '=' instead
of '+='.

I looked this up the last time I had to do that [ (for the more involved
Makefile for the RInside examples) -- in that case I went the other way (per
Writing R Extensions / CRAN Policy) and just renamed the Makefile to
GNUMakefile. ]   There is some documentation on-line, but "portable make" is
truly restriction. No shell, no if, ...

Maybe  cat("\n", append=TRUE, con=fileconnection)    ?

Also remember that you can test against R-devel by submitting to win-builder.
