I think the two test cases are not related at all, the second one only needs to fold strchr ("<12ers", '1' ) 
to 1 (which it does when expanding to RTL).  There are two problems with the first testcase, first 
"<12ers" + 1 == 0 is "folded" to "<12ers" == -1 by fold, and but if you add a tempary variable then "< 
12ers" + 1 == 0 is not folded to false.  Confirmed otherwise, the orginal testcase is not done on the 
RTL level but the other two are.
