-------------------- 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.
