I did something like this:

test -f makerr && backup makerr; (date; ./configure \
--disable-nls --disable-shared --enable-test-coverage \
CFLAGS='-O2 -g -Wformat -Wformat-security -Winit-self -Wall -Wpointer-arith -Wextra -Wshadow -Wcast-align -Wwrite-strings -Wno-sign-compare -Wp,-D_FORTIFY_SOURCE=2 -Dlint' && make && make check && make distcheck; date ) >& makerr & tail -F makerr

Disabling nls makes it so _() is a no-op, and that exposes
the otherwise-hidden-from-gcc's-perspective literal format
strings for analysis.
