No. Though afaik only the names are set, and since (unlike with normal
units) you can exchange these files without recompiling everything, except
maybe for OS X/

I haven't really tested this for si_* though, but this has been done in the
past that allowed to fix the same binary releases to generate FreeBSD 4 or 
5 binaries, using the following scripts:

http://www.stack.nl/~marcov/fixfpc19
http://www.stack.nl/~marcov/fixfpc2

As of 2.2, these scripts are no longer supported though, since more post 4
functionality has been integrated into the RTL.
