size of executables

[Sivo Schilling]

Replay to Christian,

ok I get it. Structs are treated as POD by the compiler and therefore
have a default initializer which have to be present in the executable. 

Thanks.

> In the first case DMD will generate a default initializer for the struct which is probably what you're looking at in the DATA section. I do not think you can stop DMD from doing that - it's part of the TypeInfo instance it generates for the struct.
