Since v2.3.0-rc1-37-gf18604b we've been using setlocale() here without
importing locale.h. Oddly enough this only causes issues for me under
-O0 on GCC & Clang. I.e. if I do:
$ git clean -dxf; make -j 1 V=1 CFLAGS="-g -O0 -Wall" http.o
I'll get this on clang 3.5.0-6 & GCC 4.9.1-19 on Debian:
http.c: In function ‘get_preferred_languages’:
http.c:1021:2: warning: implicit declaration of function ‘setlocale’
[-Wimplicit-function-declaration]
retval = setlocale(LC_MESSAGES, NULL);
^
http.c:1021:21: error: ‘LC_MESSAGES’ undeclared (first use in this function)
retval = setlocale(LC_MESSAGES, NULL);
But changing -O0 to -O1 or another optimization level makes the issue go
away. Odd, but in any case we should be including this header if we're
going to use the function, so just do that.
