Compilation warning in simple-object-xcoff.c

[Eli Zaretskii]

Compiling GDB 8.0.91 with mingw.org's MinGW GCC 6.0.3 produces this
warning in libiberty:

     gcc -c -DHAVE_CONFIG_H -O2 -gdwarf-4 -g3 -D__USE_MINGW_ACCESS  -I. 
-I./../include   -W -Wall -Wwrite-strings -Wc++-compat -Wstrict-prototypes 
-pedantic  -D_GNU_SOURCE ./simple-object-xcoff.c -o simple-object-xcoff.o
     ./simple-object-xcoff.c: In function 'simple_object_xcoff_find_sections':
     ./simple-object-xcoff.c:605:25: warning: left shift count >= width of type 
[-Wshift-count-overflow]
          x_scnlen = x_scnlen << 32
                         ^~

And indeed x_scnlen is declared as a 32-bit data type off_t.

I'm willing to test patches if needed.

Thanks.
