and so on - fixdep has changed, and on my alpha, it now has 'unaligned

Of course, 2.5.21 won't compile at all, but still, this is a regression.

This seems to be caused by line 364 of fixdep.c:

alpha:/usr/src/linux-2.5.21# /home/jurriaan/unalign scripts/fixdep scripts/lxdialog/checklist.o /usr/src/linux-2.5.21 gcc -Wp,-MD,scr
ipts/lsdialog/.checklist.o.d -g -c -o scripts/lxdialog/checklist.o scripts/lxdialog/checklist.c

fixdep(15767): unaligned trap at 0000000120001d48: 000000012000210a 28 3

Program received signal SIGBUS, Bus error.
0x120001d48 in traps () at scripts/fixdep.c:364
364 if (*(int *)test != INT_CONF) {
(gdb) bt
#0 0x120001d48 in traps () at scripts/fixdep.c:364
#1 0x120001de8 in main (argc=10, argv=0x11ffffc58) at scripts/fixdep.c:375

I'm not expert enough in C to suggest a solution for this, but I'm
willing to test.

Good luck,
