After way too long, I'm finally getting around to upgrading from
Emacs 21.3.1 to Emacs 23.4.1. I downloaded the precompiled Windows
unpacked it, and created a Windows shortcut to bin/runemacs.exe.
The OS is Windows XP SP3.|
When I start up the new version, it finds that I've got an
initialization file at C:/.emacs, and it looks like some of the Lisp
code that works under 21.3.1 no longer works under 23.4.1. For the
moment I want to keep both versions installed. Is there some way to
have the different versions initialize themselves from different
.emacs files? Alternatively, is there some Lisp code I can insert
to test which version of Emacs is running, so I can conditionalize
the code to do the right thing for each version?
