Have you downloaded and uncompressed the R sources? rw0613s.zip
is just an add-on. ../appl/ROUTINES is in R-0.61.3.tar.gz.
If you expand R-0.61.3.tar.gz somewhere and then rw0613s.zip
in R-0.61.3, you should get a directory tree like this
R-0.61.3 -- afm
	    src -- appl
		   library -- base
		              eda  -- src

FFDecl.h is generated by the command in the Makefile that gave you
an error.

The main make runs in R-0.61.3/src/gnuwin32.
To build package xxx (e.g. eda), you find in the Makefile  a rule of the type
make -C ../library/xxx -f ../../gnuwin32/MakePkg PKG=xxx .................
Hence, this sub-make is executed in the ../library/xxx directory,
but in MakePkg you find a rule of the type
make -C ./src -f ../../../gnuwin32/MakeDLL .................
So, the sub-sub-make which build the shared library is executed 
in ../library/xxx/src (path starting from the gnuwin32 directory).
Now MkRule (this file is not R-specific but contain the rules
for compiling .c and .f file + building relocable executable
and dll) and lib_iR.a (the import library for R.exe) are
in the gnuwin32 directory. This is why they must prefixed by

I hope this can help (and that my English is not too obscure).
