+- Update to 1.6.3
+  + Fixed a memory leak when deduplicating paths.
+  + Fixed strndup-related build regression on Windows.
+  + Added --modversion description to pkgconf(1) man page.
+  + Properly tokenize versions. Versions cannot logically contain
+    whitespace, as dependency-lists would not properly tokenize if
+    they could. A diagnostic is generated for malformed version
+    strings containing whitespace when --validate is used.
