Compiling an empty form, smartlink, withdout heaptrc, and stripped (use
strip.exe) should come to 1.9 Mb on Lazarus trunk.
To get it further down, find initialization sections throughout the LCL,
and disable stuff you do not need.
e.g. graphics uses units for the different gfx formats, if you do not
use png, comment out the registration (though I am fot sure what is
needed for icons...). That can save a few 100K if you are lucky. (Having
that in, is the price for using RAD) (I did test this one a few years back)
Not sure, not tested, but you may also find resources included (such as
icons) and decide you can do without, or with less. (Only guessing....)
