I've release mingwrt-3.20-2 to address an issue when compiling with GCC 4.7.0.
The '-2' release includes a back ported patch from CVS to address a
crash in the startup code when compiled with GCC 4.7.0. Many thanks
go to Cesar Strauss for tracking down the source of the crash and
subsequently pulling the appropriate patch out of CVS
