[Rd] Build package for R 2.0.1 under Windows

[Per.Broberg at astrazeneca.com]

This summer I and a colleague built a package for R v 1.9.1 containing
C-code under Windows. That only worked for us when
R was installed in c:\program files\R. Now I have R v 2.0.1 and the same
package won't build. I get the following

C:\Program Files\R\rw2001\bin>rcmd check "c:\program
files\r\rw2001\src\library\
sag"
* checking for working latex ...latex: not found
 NO
* using log directory 'C:/Program Files/R/rw2001/bin/sag.Rcheck'
* checking for file 'sag/DESCRIPTION' ... OK
* checking if this is a source package ... OK

installing R.css in C:/PROGRA~1/R/rw2001/bin/SAG~1.RCH
