the docs say:
`-O3'
     Optimize yet more.  `-O3' turns on all optimizations specified by
     `-O2' and also turns on the `-finline-functions',
     `-funswitch-loops' and `-fgcse-after-reload' options.

could you test these switches individually?
and whats the output with -Winline from both -O2 and -O4?
also the -O2 and -O4 -Winline output from the one for whom -O4 is faster would
be interresting

In the past you could go to a library and read, borrow or copy any book
Today you'd get arrested for mere telling someone where the library is
