gcc version 4.1.2 20080704 (Red Hat 4.1.2-44) generated below code.

.loc 1 51 0
movl -48(%ebp), %eax # start.1059,
movl -44(%ebp), %edx # start.1059,
addl -24(%ebp), %eax # size,
adcl -20(%ebp), %edx # size,
movl %eax, -56(%ebp) #, count
movl %edx, -52(%ebp) #, count
subl %ebx, -56(%ebp) # last_bad.1061, count
.LVL28:
sbbl %esi, -52(%ebp) # last_bad.1061, count
movl -56(%ebp), %edx # count,
movl -52(%ebp), %ecx # count,
shrdl $3, %ecx, %edx #,,
shrl $3, %ecx #,
movl %edx, -56(%ebp) #, count
movl %ecx, -52(%ebp) #, count

It seems that only gcc 3.x genarates "call __udivdi3" ...
