Subject: Try to fix libfat/ulint.h for non-x86 platforms
X-Git-Tag: syslinux-3.53-pre1~1
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=0791bf3c88f8f639e367bc2edd5f181c41e7e42b;p=profile%2Fivi%2Fsyslinux.git

Try to fix libfat/ulint.h for non-x86 platforms

libfat/ulint.h doesn't work as expected because of array devolution to
pointers.  Try to fix.
