Continuing their abusing of well defined keyword from other languages.

In C weak means
  - for externals: if the linker does not find the reference it writes a 
NULL instzead of aborting the link process with an error message.
  - for globals: if the linker finds another global of this name it does 
not use the weak ones. It aborts when it finds duplicates that are both 
non-weak.

not similar at all :-(
