This is possible - both affected systems, the F7 system refered to above - 
documented here:

and an odd problem on a Cygwin 6.2.3 installation
(key modules do not write to stderr or stdout, documented in: 
http://spatial.nhh.no/misc/cw.png) - problem started after updating cygwin 
packages last night,

have odd/stale things in the GRASS_LD_LIBRARY_PATH and in PATH (or LD 
path) environment variables. I don't have ldd on Cygwin, but will look 
under F7.

I was just checking a few extra systems to see how the R interface worked 
on the final RC before release, that's why I'm asking.
