Correction - there are actually 3 additional warnings like this in repl_gram.c:
/home/peter/build/Release/bin/clang -O2 -Wall -Wmissing-prototypes
-Wpointer-arith -Wdeclaration-after-statement -Wendif-labels
-Wformat-security -fno-strict-aliasing -fwrapv -I.
-I../../../src/include -D_GNU_SOURCE -c -o repl_gram.o repl_gram.c
repl_gram.y:106:30: warning: implicit conversion from enumeration type

NodeTag') [-Wconversion]

I'll take a look into them later.
This tautology warning sounds completely valid:
/home/peter/build/Release/bin/clang -O2 -Wall -Wmissing-prototypes
-Wpointer-arith -Wdeclaration-after-statement -Wendif-labels
-Wformat-security -fno-strict-aliasing -fwrapv -pthread -D_REENTRANT

-DUNSAFE_STAT_OK -I. -I../../../src/include -D_GNU_SOURCE

fe-exec.o fe-exec.c
fe-exec.c:2408:13: warning: comparison of unsigned enum expression < 0

if (status < 0 || status >= sizeof pgresStatus / sizeof pgresStatus[0])
~~~~~~ ^ ~
1 warning generated.
So, there are 4 remaining warnings.
