Why? Since we have complete control of the process why put in ugly #ifdef logic? Just put the information into different files. Use of CPP is an admission that you haven't found a better way to do it :-)</blockquote>

But once you decide to make the choice at compile time, I don't see how a combinatorial number of generated files is clearly better. Matt would have us move all of PETSc into BuildSystem and generate a header that did everything. ;-)<div>
