Binary built on different platforms with exact same tools different?

Hi. I've built an xscale-elf toolchain from gcc-4.2.2, binutils-2.17,
newlib-1.15.0. I've used the exact same build procedure on both Mac OS
X 10.5 (gcc-4.0.1-based) and Cygwin (gcc 3.4-based).
Then I built our code and stripped the resulting binary with objcopy
on each platform.
Both binaries seem to run the same.
However, cmp shows many differences between the two resulting
binaries. Here are a few:
$ cmp -l ~/h h | head -10
77 21 63
81 32 74
85 27 71
97 370 220
98 162 163
101 134 364
105 134 364
141 4 15
143 55 240
144 345 341
Are these differences something to worry about?
TIA,
Rick
