FYI, I just did a grep through the code, and there are currently still 1820
instances of bzero and bcopy across about 75 packages. But you're right that
a lot of the versions of these packages are fairly out of date.

if you're looking under libc/string/<arch>/, then that doesnt represent what
you might think. those are optimized versions only. generic C
implementations exist for all string functions.

the default uClibc configuration turns off support for deprecated functions by
design. you might want to enable the macro-rewrite option rather than going
with the runtime bloat. this has the uClibc headers provide macros that
rewrite the deprecated b* functions to the equivalent mem*/str* ones.

i blame uClinux-dist for being out of date :p. personally, ive been sending
patches to people for this and everyone has accepted them ... i have no info
wrt your specific examples though.
