Normally if two functions have the same name the linker will abort
with an error. If one function is weak then it will be removed, and
the non-weak function will be used.
It is good and bad. It allows to override a general function easily,
but on the other hand it may be difficult to determine which code is
actually being used, when many functions have the same name.
