compile-related functions added, for use in Unicode-internal ws -------------------- ChangeLog entries follow: -------------------- lisp/ChangeLog addition: 2010-01-17 Ben Wing <ben@xemacs.org> * bytecomp-runtime.el: * bytecomp-runtime.el (error-unless-tests-match): New. * bytecomp-runtime.el (byte-compile-file-being-compiled): New. * bytecomp-runtime.el (compiled-if): New. * bytecomp-runtime.el (compiled-when): New. Add functions for dealing with conditional compilation of different code depending on the presence or absence of features. Necessary for some Mule code where code is run during compilation (macros or eval-when-compile) but, depending on how the code is written, the code itself will crash either with or without Unicode-internal. compiled-if and compiled-when are the basic functions for conditional compilation. They automatically trigger an error message upon file loading if, at that time, the test expression that selected which code to compile does not have the same value as at compile time.
