R devel - Oct 2010 - Missing libpthread in RTools

It appears that Mingw gcc included in RTools is missing a dependent 
library. If I compile a program with '-lgomp' switch (for OpenMP 
support), I get a errors about undefined references to functions like 
'_imp__pthread_mutex_destroy'. Adding the '-static' switch, I
get the
following error:

    c:/rtools/mingw/bin/../lib/gcc/mingw32/4.5.0/../../../../mingw32/bin/ld.exe:
cannot find -lpthread

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?
