4Subject: [PATCH] Fix tautological compare warning
5
6By default, gcc ignores warning from code generated by macros
7(https://gcc.gnu.org/bugzilla/show_bug.cgi?id=80369). When
8ltrace is compiled under icecream the warning *is generated*
9(https://github.com/icecc/icecream/issues/202)
10and the compilation fails (because of -Werror).
