Re: [pacman-dev] [PATCH] Declare all local functions static

18 Dec 2010

...
All functions that are limited to the local translation unit are
declared static.  This exposed that the _pkg_get_deltas declaration
in be_local.c was being satified by the function in packages.c which
when declared static caused linker failures.
Hmm. All of these were left this way on purpose, and the deltas thing
was obviously done on purpose too.
...
Fixes all warnings with -Wmissing-{declarations,prototypes}.
What do these warnings look like? Did the gold linker expose these,
I'm assuming?
