Well, I can try to compile packages with different options
for size, I can link against small libc, but I feel this
does not solve the problem: the code itself is bloated...

I am not a code genius, but want to help.

Hmm probably some bloat-detection tools would be helpful,
like "show me source_lines/object_size ratios of fonctions in
this ELF object file". Those with low ratio are suspects of
excessive inlining etc.

More ideas, anyone?
