On platforms where we can use weak aliases, use
__weak_alias(__errno, __errno_func);
and on platforms where we cannot, just compile the function as
__errno, since on those platforms we cannot make libc thread-safe,
at least using this trick.
Are there any platforms where we cannot do __weak_alias() anymore?
(as originally declared in System V) to "char * const []", as was done in
1003.2 and subsequently propagated into XPG4.

page needs a lot of help:
- restructure it into xdr_admin(3), xdr_complex(3), xdr_create(3), and
xdr_simple(3), as is done in Solaris.
- rewrite in mandoc, and document all of the XDR primitives that NetBSD
actually supplies.
- xdr_int64_t(), xdr_u_int64_t(), per NetBSD convention.
- xdr_hyper(), xdr_u_hyper(), xdr_longlong_t(), xdr_u_longlong_t(), a'la
Solaris, implemented in terms of the above.
* sl_add(); if realloc() fails return -1 instead of calling err(1,...).
otherwise, return 0.
NOTE: this change resulted in sl_add() changing from returning void to int.
this shouldn't be a problem because a) it returns 0 if ok (aka `void', b)
all invokers of sl_add() in the tree have been changed (mainly code i've
written).
char *
svis(char *dst, int c, int flag, int nextc, const char *extra);
int
strsvis(char *dst, const char *src, int flag, const char *extra);
int
strsvisx(char *dst, const char *src, size_t len, int flag,
const char *extra);
These functions correspond to vis(), strvis(), and strvisx() but have an
additional argument extra, pointing to a NUL terminated list of characters.
These characters will be copied encoded or backslash-escaped into dst. These
functions are useful e. g. to remove the special meaning of certain
characters to shells.
To implement the new functions, vis underwent a major rewrite. Most functions
now use a central macro, SVIS. Performance increase ~ factor 2.

I wrote for tcsh(1) three years ago.
- implement EL_RPROMPT, which allows a setting/getting of a function which
returns a string to be used as the right-side prompt.
- improve HISTORY and AUTHORS sections in editline(3).
- bump shlib minor version for EL_RPROMPT.
XXX: due to an implementation issue, the rprompt has a 1 space gap before the
edge of the logical screen. editline's logical screen is 1 space less
than the full screen width, so there's a 2 space gap between the rprompt
and the right end of the physical screen. i'm not concerned about this.
