Tried compiling Wine with -Werror, got a few interesting results. First one:

austin@austin-desktop:~/wine-git/dlls/jscript$ make
gcc -c -I. -I. -I../../include -I../../include  -D__WINESRC__  -D_REENTRANT
-fPIC -Wall -Werror -pipe -fno-strict-aliasing -Wdeclaration-after-statement
-Wwrite-strings -Wpointer-arith  -g -O2  -o engine.o engine.c
cc1: warnings being treated as errors
engine.c: In function ‘var_statement_eval’:
engine.c:500: warning: ‘hres’ is used uninitialized in this function
make: *** [engine.o] Error 1

Relevant code portion:
/* ECMA-262 3rd Edition    12.2 */
HRESULT var_statement_eval(exec_ctx_t *ctx, statement_t *_stat, return_type_t
*rt, VARIANT *ret)
{
    var_statement_t *stat = (var_statement_t*)_stat;
    HRESULT hres;

TRACE("\n");

hres = variable_list_eval(ctx, stat->variable_list, &rt->ei);
    if(FAILED(hres))
        return hres;

V_VT(ret) = VT_EMPTY;
    return S_OK;
}
