It seems reasonable that structures passed on the PAL_MC_ERROR_INJECT
PAL call be defined in pal.h.

That would explain the complexity of specifying the bit patterns of 
err_type_info and err_struct_info in err.conf.  Not the friendliest 
user interface.  Sufficient for testing/debugging but a good opportunity
for improvement.
