Chasing RAM - libc ..

[m8847]

I am a bit short of RAM in my project, so I am trying to free up as much
as
possible, and I have seen that libc uses a lot, which I am unsure about.

I have rolled my own malloc()/free(), and thus should not use any library
version of them. I hope. And I only use C-code, no C++.

These are the worst consuming bits, but maybe these are things that need
to
be around(?) (or can I somehow tweak them away?):
