+pkg-config 0.23 PKG_CONFIG_SYSROOT_DIR bug
+Paul Bender <pebender@san.rr.com>
+Tue Jan 22 20:04:41 PST 2008
+
+There appears to be a bug in the handling of the new
+PKG_CONFIG_SYSROOT_DIR. When PKG_CONFIG_SYSROOT_DIR is set, on the all
+but the -I and -L options are removed from --cflags and --libs
+respectively. This does not seem like the right behavior.
+
+I have attached a patch that fixes the problem for me.
