So i ended up with a 32-bit kernel that tried to build a 64-bit piece of code - fireworks. That condition persisted - i had to fix it up manually all the time i integrated that portion of the tree. That too was i think centered around a header file chunk - perhaps the #include section of traps_32.c and traps_64.c was similar enough in that section?
