+- Version update to latest release 4.24:
+  * bump version to 4.24, as the release tarball inexplicably
+    didn't have the right version in ev.h, even though the cvs-tagged
+    version did have the right one (reported by Ales Teska).
+- Version update to release 4.23:
+  * move some declarations at the beginning to help certain retarded
+    microsoft compilers, even though their documentation claims
+    otherwise (reported by Ruslan Osmanov).
+- Run over with spec-cleaner and remove empty comment lines
+- Remove mandriva condition

 A full-featured and high-performance event loop that is loosely modelled after
