   Comparison of your GDB session with mine shows that each time a .el

   your machine, sometimes only by 1KB, sometimes by as much as 20KB.

Of course, using different compilers or different C Libraries,
_including_ different version numbers for the same compiler or library
will not have any effect on the .el file, but it can definitely have
an effect on the .elc files.  Different OS or different versions of
the same OS of course also can make a difference.  As I already
mentioned, talking about KB is meaningless in this context, this is
about average percentages.  Nearly 13 percent seems indeed to be
somewhat to the large side.  On the other hand a difference of less
than one percent, like the difference between our two numbers for 32
bit (which we discussed before) seems to be well within the bounds of
what is to be expected and hence completely meaningless.  But maybe
variations tend to be larger for 64 bit than for 32?

Sincerely,

Luc.
