Well, you're assuming that I can either guess from your command lines why
something is larger, or that I have some magical program which can read a
binary you give me.  Depending on your system I may or may not have such
a magic utility.

Far better for you to look at these things yourself since you have the binary,
and utilities which can look at the size of the various sections within the
binary.

EH, debugging & shared libraries again.  

run objdump -h on the big and small versions of your program.  Then look
at the output for sections which are much better in one than the other.

Also verify that each version is linked in the same manner (either statically 
or dynamically).
