I checked compiler warnings using COPT=-Werror, but it detects warning on
only unrelated files as below. Does it really come from my patches?
(Does it depend on ./configure options?)

gcc -O2 -Wall -Wmissing-prototypes -Wpointer-arith
-Wdeclaration-after-statement -Wendif-labels
-Wmissing-format-attribute -Wformat-security -fno-strict-aliasing
