I see the same behavior with the official 0101E0009 build and the Stellaris Launchpad.
Looks like there was a major overhaul of wiring.c since then that might fix the issue. Unfortunately I couldn't get the newer version to work for me. Grabbing wiring.c alone seems to completely screw timing (i.e. Serial doesn't work anymore), and grabbing larger parts of the hardware folder causes compile errors about a missing syscalls.h.
