the renamed functions, and add some #error directives to force the
issue with weak symbols for renamed functions when we support weak
symbols in the C library.
with roots consisting of a single slash. This special case of special
cases cannot be dealt with in fts_open() by simply chopping of a
trailing slash.
All this to avoid the occasional doubling of slashes. Oh well..
messes up the internal administrations of the fts engine.
Do this differently by simply stripping one trailing slash (if any)
from root paths passed to fts_open().
identifier namespace by renaming non standard functions and variables
such that they have a leading underscore. The library will use those
names internally. Weak aliases are used to provide the original names
to the API.
This is only the first part of this change. It is most of the functions
which are implemented in C for all NetBSD ports. Subsequent changes are
to add the same support to the remaining C files, to assembly files, and
to the automagically generated assembly source used for system calls.
When all of the above is done, ports with weak alias support should add
a definition for __weak_alias to <sys/cdefs.h>.
