Ahh, OK.

Related query -- is there any way of telling the compiler 
(gdc/gdmd or preferably any of the D compilers) to strip out 
unused symbols/functions/data from the binary?

I have a module that includes a quite large array of immutable 
data (used for test purposes), but when this is compiled in 
with other code it adds about 10MB (!) to the executable size, 
even when the executable never uses it.

It is exactly what `gdc -fdata-sections -Xlinker --gc-sections 
app.d` will do.

Be careful though, if you use dynamic loading of shared libraries 
(or build your app as library) that may result in weird stuff 
when applied to all sources :)
