You didn't tell enough to answer that.  First, are those programs
stripped?  In other words, did you run `strip' on them, or used -s
option when linking?  If not, they include debugging info which might
be larger in later versions (more debugging info generally means
better debugging).

If they are stripped, you need to tell which switches did you use when
compiling.  Some switches can have different effects with different
compiler versions.  For example, if you use -O3, the amount of code
inlined by the compiler could change with the versions.

Also, how large are the programs?  Some bloat might be due to
different alignment of the code/data.

In short, tell more.
