[R] RTools and previous Cygwin installation--conflict?

[Brent]

Duncan: so good to get a reply from the RTools maintainer! I decided for now to go with your simplest suggestion 1.  So, I deinstalled 64 bit cygwin, 
reinstalled the 32 bit version, and hope that the RTools versions of the commands which will get picked up earlier in the PATH will not cause my cygwin any problems.


Gabor: if I ever find Duncan's 
suggestion 1 inadequate, such as if I really need 64 bit cygwin, then I 
will adapt one of your scripts.  Your scripts, by the way, deserve 
special commendation: the code is beautiful, which is no easy feat in 
DOS...
