<nmath.h> ?

It's clear to me at least that this particular solution is absolutely
not what customers want.  The last thing numerically-oriented customers
want to do, in general, is rewrite their source code.  They just want
to recompile and run faster.  That argues for other solutions,
such as compiler options that cause linking with alternate libraries.
Changing Makefiles is odious to many people but less so than 
changing the source.
