Trying to build mob on RPI I now get this new warning

gcc -c ./lib/libtcc1.c -o libtcc1.o -DTCC_TARGET_ARM -Wall -g -O2 -Wdeclaration-after-statement -Wno-pointer-sign -Wno-sign-compare -Wno-unused-result -fno-strict-aliasing -I.  -fPIC
./lib/libtcc1.c: In function __fixunsxfdi:
./lib/libtcc1.c:586:26: warning: dl1.l.upper is used uninitialized in this function [-Wuninitialized]
     if (dl1.l.lower == 0 && dl1.l.upper == 0)

unsigned long long __fixunsxfdi (long double a1)
    register union ldouble_long dl1;
    register int exp;
    register unsigned long long l;

    dl1.ld = a1;

    if (dl1.l.lower == 0 && dl1.l.upper == 0)
        return (0);

And union is defined as:

/* only for x86 */
union ldouble_long {
    long double ld;
    struct {
        unsigned long long lower;
        unsigned short upper;
    } l;
