How much smaller?  Is it smaller by 2048 bytes?  If so, that's because 
the default target for ld is to create a .exe-style executable (you 
should see the characters `M' and `Z' as the first two bytes of test2).  
OTOH, test1 is an unstabbed COFF file, which doesn't include the 2KB-long 
stub.

I think the default alignment is also different from what the linker 
script says, which might explain additional differences.

Btw, it is only natural that you get different results with and without 
the script, otherwise it would be superflous, right?

Uninitialized data gets into that section.
