Thanks for investigating, and sorry that this proves a worthy opponent!

On my testers, the system compiler used for bootstrap is GCC 4.2.
Could that make a difference?

Also, comparing stage2-libiberty/fnmatch.o  and stage3-libiberty/fnmatch.o
I noticed that the latter is more than three times the size.

objdump -d does not show any difference.  objdump -W, however, shows
lots of additional DWARF debugging information.  I am attaching a diff 
between the two.

Does that help?

Gerald
