+The problem is that unsigned char[2] is
+guranteed to be 8Bit aligned on arm
+but unsigned short is/needs to be 16bit aligned
+the union { unsigned short; unsigned char[2] } trick
+didn't work so no we use the alpha hack.

+memcpy into an 16bit aligned

+Upstream-Status: Inappropriate [licensing]
+We're tracking an old release of dosfstools due to licensing issues.
