I highly recommend picking one version of gcc and using that version only.
If you switch versions, you should probably start over, recompiling 
everything.

This seems to say that part of your gcc installation is missing.  Use the
command "cygcheck -c" to see what gcc is installed and to verify that
the files required are present.  Remove and reinstall any damaged packages.
Remove any gcc/g++ versions other than the one you choose to use (only
3.4.4-999 is currently known to work with GNU Radio).  Be prepared to
rebuild any dependencies that you might have built with another compiler.
