So starting a new Rcmd.exe process fails for some reason.

If you take the same R session where the environment variables are
right and Sys.which() resolves Make and GCC and try to run
tools:::.shlib_internal(c('-n', 'hello.c')) or
tools:::.shlib_internal('hello.c'), does it do something useful?

(I'm still debugging from first principles. Duncan Murdoch is likely
right that adding the environment variables, either
RTOOLS43_HOME=c:/rtools43 or adjusting PATH as described above, could
help.)
