There were many problems with -masm=intel, that were fixed for gcc-4.3 and
later by [1] and (many) followup patches. The change that you are looking for
is (gcc/config/i386/i386.c):

switch (GET_MODE_SIZE (GET_MODE (x)))
However, this is just one of many changes to properly support -masm=intel, so
my best advice is to use gcc-4.3.x. This won't be fixed for gcc-4.2.
