* But there is also a disadvantage of the \ifeof18 method: TeX generates a error message, if \ifeof18 is not supported. Unhappily TeX does not provide an exception mechanism, so this error cannot be catched. For "tex" and "etex" I see no way to avoid this without a new primitive that can easily checked for existence. The primitive can be either a command that indicates the presence of the feature or returns the version number of web2c. For "pdf(e)tex" this is not a problem, because here \pdfversion and \pdfrevision can be asked. So packages such as pdftricks, pdftex.def, ... will be happy.
Isn't there a new version of tex coming (dek posted some fixes)? In that case, one can use that version number since the moment that those fixes are in the new distribution sync with the ifeof18 extension.
