I always assumed it wasn't permited - perhaps it is. You have been bamboozled nu the wording. No one can forbid an implementation to add a facility like this. The wording is such to scare implementors like me. Note that this doesn't interfere at all with compliance to the standard. If it is common place to add nested compilation they have to add this sooner or later. The prize is a non-standard program. Point me to a program that does something useful, and doesn't contain implementation dependant parts. Now it is a good time to recapitulate my postings "The four brackets of the apocalypse." A good test of whether an architecture is sound, is whether fullfilling such request is easy. I'm proud that in all programs I designed,reasonable extension were easy. A similar situation applies to "TO must scan". It turns out there is no standard program that can detect this. It steers implementation towards a scanning TO. <SNIP> >-- >Gerry Groetjes Albert -- The Chinese government is satisfied with its military superiority over USA.
