Please note that discussion about the V2 alpha should be on the
djgpp-v2 AT delorie DOT com mailing list, not the general list, until the
beta is released.

V2 includes the extension logic in the application, making it bigger
than V1 programs. However, the stub is much smaller, which helps to
even that out.
Your program is big for two reasons:
1. It includes the symbol table. Stripping that off will reduce the
size of the exectuable.
2. Depending on which snapshot you have, you might be linking in far
more code than you need for a simple program. Just last night I
trimmed 18K of the size of the smallest program "main(){}". If you
don't need command-line processing, you can remove that, and if you
don't use environment variables, you can remove djgpp.env processing.
Doing both of these results in a minimum size of 15K for the basic
program. Most of this is exception handling and libc routines, and
reducing this further will be an ongoing project.
