ModuleInfo and -fno-moduleinfo option

[Marius Cristian Baciu via Digitalmars-d-learn]

Hello,

As a general question, what is the purpose of ModuleInfo, 
constructing and deconstructing each of the runtime's modules? In 
other words, what are the ramifications of using gdc's 
-fno-moduleinfo option?
I am asking this because I found that skipping its generation 
solves the problems generated by DSO registration in environments 
with no knowledge of a dynamic linker. However, I doubt this was 
among the initial motives for creating this compiler option and I 
would like to be aware of all implications.

Thank you,
Cristi
