It grows as soon as certain pages are accessed. And - as already said - 
unless the distinct functional (sub)modules are aligned into their
own pages instead of randomly cat'ed to one big contigious text section 
on linker's will, there's great chance that there're many, many 
never-accessed areas within pages that still have to be accessed
(and thus loaded).

I'm not talking about creating many configuration options, but
actually moving out functional modules to dedicated libraries.

For me, too, as soon as I understood the total ignorance of constraints 
and QM requirements in embedded systems. 

That's just self-explaining:

excalibur gtk+-2.18.9 # find -type f -exec "grep" "-E" "AC_TRY_RUN|AC_CHECK_FILE" "{}" ";" | wc -l
8
