+2005-11-27  Matt Johnston  <address@hidden>
+
+	* Makefile.am, configure.ac, pch.hh: add --enable-pch configure
+	flag to enable precompiled boost headers. Based on LyX automake/autoconf
+	rules, Zbynek Winkler suggested that just boost headers would be
+	beneficial.

 2005-11-26  Nathaniel Smith  <address@hidden>
 
 	* UPGRADE: Add note about serve changing syntax.
