Provide explicit LC_C_LOCALE accessor and drop the various NULL checks.
Provide LC_GLOBAL_LOCALE in a way that works with all locale functions.
Merge constant data used by the initial global locale and the C locale.
Drop function call layer for _current_locale() and directly return the
locale reference, not a pointer to it. Use protected access for global
variables, so that libc references can avoid the GOT overhead.

Add new line at the end.

Add scanf_l and wscanf_l families.

- widen the internal read and write calls to match the syscalls
- add funopen2() which provides access to flush() and the wider calls.
- make use of the new flush call in fmemopen()

- ansify, knf.
- no functional changes

PR/45989: Martin Husemann: lint invocation does include -w only on i386

- turn lint -w for all the platforms after fixing the lint warnings.
- add _DIAGASSERTS() for casts that would assign values to types that
would not fit.
- change types, add casts
- change into ansii prototypes
- turn on _DIAGNOSTIC for libc (during current, to be eliminated for release
builds)

Use a proper char */size_t pair in __sfileext to keep track of the line

Nobody tested this? Initialize wcio for wide char i/o.
NB: Pullup to 5.0.

remove an unnecessary __UNCONST.

WARNS=4

Add the missing wide char support functions from freebsd.
XXX: long double support is missing until we get gdtoa, and add the
necessary wide functions.
