+Subject: [PATCH] qmake: Always split QMAKE_DEFAULT_LIBDIRS using ; with clang
+ on windows
+
+When building in a unix style build system (i.e. msys), QMAKE_DIRLIST_SEP
+is a colon, not a semicolon. Thus, always split the incoming string
+(after the fixup regex) using semicolons on windows.
+
+This matches the code for gcc, further up, which does:
+
+    equals(QMAKE_HOST.os, Windows): \
+        paths = $$split(line, ;)
+    else: \
+        paths = $$split(line, $$QMAKE_DIRLIST_SEP)
+
