really shouldn't be exported since they should be pulled from libgcc, but
the build of some applications is broken and they expect to see them in
libc. glibc exports these symbols, although Solaris doesn't appear to,
so export them for compatibility's sake.
After discussion with: kan
net: endhostdnsent is named _endhostdnsent and is
private to netdb family of functions.
posix1e: acl_size.c has been never compiled in,
so there's no "acl_size".
rpc: "getnetid" is a static function.
stdtime: "gtime" is #ifdef'ed out in the source.
some symbols are specific only to some architectures,
e.g., ___tls_get_addr is only defined on i386.
__htonl, __htons, __ntohl and __ntohs are no longer
functions, they are now (internal) defines in
<machine/endian.h>.

Warning, after symbol versioning is enabled, going back is not easy
(use WITHOUT_SYMVER at your own risk).
Change the default thread library to libthr.
There most likely still needs to be a version bump for at least the
thread libraries. If necessary, this will happen later.
passed storage buffers rather than using static storage. Reimplement
ether_ntoa() and ether_aton() in terms of these functions. These variants
are thread-safe.
Not because I admit they are technically wrong and not because of bug
reports (I receive nothing). But because I surprisingly meets so
strong opposition and resistance so lost any desire to continue that.
Anyone who interested in POSIX can dig out what changes and how
through cvs diffs.
(also IEEE Std 1003.1-2001)
The specs explicitly says that altering passed string
should change the environment, i.e. putenv() directly puts its arg
into environment (unlike setenv() which just copies it there).
It means that putenv() can't be implemented via setenv()
(like we have before) at all. Putenv() value lives (allows modifying)
up to the next putenv() or setenv() call.
compatibility with the different environment conventions" (man page).
With the standards, we don't have them different anymore and
IEEE Std 1003.1-2001 says that
"The values that the environment variables may be assigned are not
restricted except that they are considered to end with a null byte"
Issue 6 (also IEEE Std 1003.1-2001) in following areas:
args, return, errors.
Putenv still needs rewriting because specs explicitly says that
altering passed string later should change the environment (currently we
copy the string so can't provide that).
