I compiled MSEide with FPC 2.4.4 and Delphi 7 for comparison.

Delphi 7:
Borland Delphi Version 15.0
Copyright (c) 1983,2002 Borland Software Corporation
303079 lines, 5.31 seconds, 2256556 bytes code, 820297 bytes data.
Exe size: 3.2MB

Free Pascal Compiler version 2.4.4 [2011/04/23] for i386
Copyright (c) 1993-2010 by Florian Klaempfl
302251 lines compiled, 45.2 sec , 2257728 bytes code, 1688152 bytes data
187 warning(s) issued
315 note(s) issued
Exe size: 3.87 MB

Interesting the big difference in data size.
