+Subject: [PATCH] ICU-20080 Avoid strange compiler behaviour in ASSERT_EQUAL()
+ macro.
+
+Using temporary variables for the two values to be compared here makes
+GCC compile the code just like we expect it to. (What it really is that
+it otherwise does on some architechtures remains a mystery.)
+
+This will make the tests pass as expected also on IA-32 with GCC.
+
+It'll also make it possible to revert the old workaround for SPARC
+introduced by commit 5b0592af79c7601d08cafcbbc7b71077faeb7e4f.
+
+Tested:
