all_SRE_edited.c and all_SRE_edited.h are auto generated by [dbcc](https://github.com/howerj/dbcc) via `dbcc all_SRE_edited.dbc`, see Makfile. all_SRE_edited.dbc is edited from all_SRE.dbc by deleting some lines to make dbcc work, not sure why those lines need to be deleted, maybe there's a better way.
