[Rd] Environment variable MAKE not defined on Windows

[Martin Morgan]

On Windows,

> Sys.getenv("MAKE")
  MAKE 
"" 

when (at a DOS prompt)

X:>set MAKE
Environment variable MAKE not defined

On linux,

> Sys.getenv("MAKE")
  MAKE 
"make" 

even when (in a shell)

% echo $MAKE

returns nothing.


This has consequences, e.g., in buildVignette where

system(Sys.getenv("MAKE"))

dutifully does nothing on Windows, but evaluates the vignette Makefile
on linux.
