* Use public API, don't access struct archive directly. (People should be able to copy these into their applications as a template for custom I/O callbacks.)
* Set "skip" only for regular files. ("skip" allows the low-level library to catch attempts to add an archive to itself or extract over itself.)
* Simplify the write_open functions by just calling stat() at the beginning. Somehow, these functions had acquired some complex logic that tried to avoid the stat() call but never succeeded.

file. This doesn't happen in normal use, because the file I/O and
decompression layers only pass through smaller blocks. It can happen
with custom read functions that block I/O in larger blocks.
* Actually use the HAVE_<header>_H macros to conditionally include
system headers. They've been defined for a long time, but only
used in a few places. Now they're used pretty consistently
throughout.
* Fill in a lot of missing casts for conversions from void*.
Although Standard C doesn't require this, some people have been
trying to use C++ compilers with this code, and they do require it.
Bit-for-bit, the compiled object files are identical, except for
one assert() whose line number changed, so I'm pretty confident I
didn't break anything. ;-)
h_errno is not an extern int, just a macro providing an integer lvalue.

Remove the const qualifier from ap argument for __v2printf, that induced
that breakage, and seems to be the real reason for bad code. ap is modified
inside the __v2printf body by va_arg macro.

i386 with default optimization level (-O2), va_list pointer ap in the
__v2printf function is advanced before the use. That cause argument
shift and garbage instead last argument in printf-family when xprintf is
activated.
The nsswitch is easy victim of the bug.

Issue __sflush() before possible setting O_APPEND mode or ftruncate(),
write to wrong place may occurse oserwise.
Use simplified _sseek() to the start, if no O_APPEND is set, instead
of _fseeko() (_sseek() to the end, if O_APPEND, occurse later, as for
file != NULL).
Don't check seek error return, as original fopen() and freopen() never
does.
file != NULL:
Add missing _sseek() to the end.
