[R] Error building R 2.14.0 from sources on Win7 x64

[Frédéric Fournier]

Hello everyone,
I'm trying to build R 2.14.0 from source on Win7 x64 using the
instructions from "R Installation and Administration" (version
2.13.2), but when I try to make the core files (as of step 3.1.3 of
the instructions), it fails with the following error:

...

-I../../include -DGA_DLL_BUILD -DENABLE_NLS=1  -O3 -Wall -pedantic

make[3]: *** [rlibs] Error 1
make[2]: *** [../../bin/x64/R.dll] Error 2
make[1]: *** [rbuild] Error 2

As anyone stumbled on this problem before? Any idea what I can do to
solve this problem?

Thank you very much for your help!
