different size of own build packages in comparing to repository' ones

[debuser <debuser@yandex.ru>]

I have an emdebian grip mirror and I'd like to build all packages from
sources.
Arch: i386

I use emdebuild -a i386 for that.

For example, I'm trying to build a a2ps_4.14 package.
After the process is finished I have  a2ps_4.14-1em1_i386.deb, 
but it's size is 675740 when the size of a2ps_4.14 package from
repository is 682004.

Is it normal ? the same situation with many other packages.


Best regards.
