1) Swapping to c++ instead of assembly implementations of several kernel APIs to avoid calling probably broken implementations of __EH_FRAME_?? macros 2) Commenting out otherwise unavoidable calls to __EH_FRAME_?? macros in uc_exe.cia. This is a temporary hack. Both changes to see if they get past an early kernel panic in the Syborg ROM from the current build: EH ERROR: no exception descriptor for address 0x801eb277 Thread efile.exe::Main Panic USER-EXEC 3
