The original source of these problems was Guido's port of R, so you
may want to pick up R-0.61.3 and his patches from a nearby CRAN site,
e.g. http://cran.stat.wisc.edu/
                                                 
I suspect that the problem was that the resource file did an 

#include <windows.h> 

which kills windres at the 1st typedef (is that a bug, BTW?) - this
happens when crosscompiling too. Then with the receiving end of the
pipe dead, the pipe spills into stdout.
