i'm guessing you're referring to the assembly of some fixed code file ?  that 
happens when timestamps get out of whack.  i originally just wanted to add a 
.h, but people requested i also add the source .s.

not sure if there's a way i could put this logic behind "if (file does not 
exist) || (file is out of date && maintainer mode)" so it doesn't bite people 
randomly ...

since we don't have a large body of people clamoring for sim device support 
under Windows, let's start with the simple version and avoid hardcoded lists.

i was thinking of a /* TODO: ... */ in each device model file that 
unconditionally uses dv-socker.  e.g. sim/mips/dv-tx3904sio.c.
