Yes, and in many other places, including native Windows binaries.

Obscureness is in the eye of the beholder, but the first step is to get
familiar with the OS before passing judgement.

That file is not mentioned in the current readme.packages (sic), by the
way, which says

`We recommend that you use the mingw32 port of gcc-2.95 by Mumit Khan from
ftp://ftp.xraylith.wisc.edu/pub/khan/gnu-win32/mingw32. ...

It is also possible to use earlier mingw32 compilers or cygwin-b20.1
with the --no-cygwin flag, but we suggest you do so only if you have a
working setup from building earlier versions of R.  We have also
successfully used the variant of mingw32 that uses the MSVCRT run-time 
system (under gcc-2.95 but not earlier versions), and in the case of the
mclust library found this more successful that the standard version.'

You might find it easier to follow the advice, as we have tried
to simplify the process.
