Author: obrien Date: Wed May 30 22:23:08 2012 New Revision: 236338 URL: http://svn.freebsd.org/changeset/base/236338 Log: Deprecate the FreeBSD make's ":U" (to-upper case) and ":L" (to-lower case) modifiers for ":tu" and ":tl" from OSF's ODE, which made its way into NetBSD's make, which is the source for the Portable Berkeley Make.
