Unless my point was not clear from my previous posts, I advocate exact
opposite: to unhide all standard symbols from libc, including here
standard prefixes like str*. We must not encourage programmer error 
when he define standard function, it easily leads to unexpected results. 
Better reject such error automatically at the linkage stage. Programmers 
are always free to redefine their functions in case of conflict.
