Indeed.

I haven't followed all this, but am somewhat bemused by it.

There are frequent complaints about Fortran due to the x86 register
business.  All the ones I've checked have been covered by the advice
in the g77 manual to link code frobbing the control word (which allows
us to pass paranoia).  Anyone know of exceptions?

[I started on implementing (as far as possible in f77-ish) the
Fortran2000 intrinsics for IEEE floating point control but gave up in
the absence of time to figure out more about the architectures which I
didn't have a clear story on.  At some stage I hope to find time to
consult Reid (the author) and do what he says.]
