it'll be mostly identical, although this depends highly on the compiler/linker.

some leave junk in the unused header sections, or padding sections.

the p.e. format (win32 exe/dll) has datetime fields, although few
linkers bother to fill it.

real comparion require disassembly... you may recall the fun the xvid
team had comparing binaries in ~aug/2002 ;-)
