It appears that Mingw gcc included in RTools is missing a dependent

following error:

Sure enough, there is neither libpthread.a nor libpthread.dll under
RTools' installation directory. I think these library are standard in
Cygwin. Is there any chance to include them in RTools, too?

Rtools is for building R, and that library isn't needed in R. If you want it for some particular purpose, can't you just install a copy on your machine?
