How can I list all of the pre#defined identifiers?
There's no standard way, although it is a common need. If the compiler documentation is unhelpful, the most expedient way is probably to extract printable strings from the compiler or preprocessor executable with something like the Unix strings utility. Beware that many traditional system-specific pre#defined identifiers (e.g. ``unix'') are non-Standard (because they clash with the user's namespace) and are being removed or renamed.
