[Question] The size of the output amx file

[scandalfive]

Hello everyone. I've encountered a situation where, when compiling an empty mod (containing only #include <open.mp> and main(){}) using qawno and a custom bat file, the output amx files have different sizes.

bat.amx - 1389 bytes
qawno.amx - 1420 bytes

Is this difference normal, or have I made a mistake in configuring the compiler command for the bat file?

bat:

Code:

compiler\pawncc.exe -;+ -(+ -\ -Z- "-isource/%name%" "-rsource/%name%" "-icompiler/include" -d3 -t4 "-orelease/gamemodes/%name%" "source/%name%.pwn"

qawno:

Code:

./pawncc -;+ -(+ -\ -Z- "-i%p/%o" "-r%p/%o" "-i%q/include" -d3 -t4 "-o%p/%o" "%p/%i"

May the experts forgive me, because this question may be very easy, but I'm new to this and I want to understand everything.
Thank you.
