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 
fails :-(

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 
just

#include

with no file name specified.

Any ideas?

Thanks, John.
