Almost.... unfortunately it appears that regardless of whatever name you
specify for the pch file Intel appends an "i" to the name, so now it
generates a file with the .pchii extension and so dependency checking still

Hmm, I put those at the end of the intel-win.jam file, and they appear to
not get called as I'm still seeing the warning?
Ah, adding the get-rspline and compile.c++.pch rules as well does cause the
overrided actions to get called, but with apparently invalid arguments
because the pch file no longer compiles: the generated .cpp file contains
with no file name specified.
