What I have done to build R from a bash cygwin window under Windows 2000:
(1) put the "tools" directory and the MinGW directories ahead of any cygwin directories on the path
(2) rename the cygwin1.dll that was in the "tools" directory (from Brian Ripley's tools.zip) to something like "Xcygwin1.dll" (to avoid cygwin conflicts)
I also have ActiveState Perl installed and ahead of the cygwin perl on the path (though I have a wrapper for it that translates cygwin paths on the command line to windows paths).
This configuration is different from the instructions in src/gnuwin32/INSTALL in that I don't use the cygwin1.dll from tools.zip. However, since updating some things recently, having cygwin1.dll in the tools directory always resulted in the "cygwin1.dll conflict" error, even when I changed the PATH to not have any other version of cygwin1.dll on it.
This may or may not work for anyone else, but it seems to be working for me at the moment: I can build R and the recommended packages from source and run the tests.

I've been attempting to create a new R package and recently removed the cygwin installation from my machine since R requires the use of the MingW tools for building an R package with C code. However, when I tried to build a source package, I found the following results:
* removing junk files * building 'Rconifers_0.7-1.tar.gz' tar: /cygdrive/C/usfs/psw_redding/software/current/Rconifers_0.7-1.tar: Cannot open: No such file or directory tar: Error is not recoverable: exiting now tar: /cygdrive/C/usfs/psw_redding/software/current/Rconifers_0.7-1.tar: Cannot open: No such file or directory tar: Error is not recoverable: exiting now tar: /cygdrive/C/usfs/psw_redding/software/current/Rconifers_0.7-1.tar: Cannot open: No such file or directory tar: Error is not recoverable: exiting now Rconifers_0.7-1.tar: No such file or directory
C:\usfs\psw_redding\software\current>
which looks like the cygwin path is hard coded into the build script for the rcmd. I found the
if($WINDOWS) { ## workaround for paths in Cygwin tar $filepath =~ s+^([A-Za-x]):+/cygdrive/\1+; }
in the build script and don't think it needs to be there since you can use the tar utility that comes with mingw, yes? I replaced the previous chunk of code with:
if($WINDOWS) { ## workaround for paths in Cygwin tar $filepath =~ s+^([A-Za-x]):+/\1+; }
which has solved the problem. I just don't know how to get this into the latest build or release of R?
Jeff.
