Also, if you're ok with changing them, I suppose you wouldn't mind
changing EF_SH4_NOMMU_NOFPU to 0x13?  We have some internal code, yet
to be contributed, that already uses 0x12, and it would suck to
introduce a binary incompatibility at this point.

We should probably discuss some protocol to enable us to reserve new
numbers in advance.

BTW, the ChangeLog entry of the patch installed on 2004-03-03 says
2003-03-03.  Oops :-)
