class. This is necessary in order to implement tr(1) efficiently in
multibyte locales, since the brute force method of finding all characters
in a class is infeasible with a 32-bit (or wider) wchar_t.
code. <whew!> This version handles all of the following edge cases:
* Restoring explicit dirs with 000 permissions (star fails this test)
* Restore of implicit or explicit dirs when umask=777
(gtar and star both fail this test)
* Restoring dir paths containing "." and ".." components
This version initially creates all dirs with permission 700 (ignoring
umask), then does a post-extract "fixup" pass to set the correct
permissions (which may or may not depend on umask, depending on the
restore flags and whether it's an explicit or implicit dir).
Permissions are restored depth-first so that permissions within
non-writable dirs can be correctly restored. (The depth-sorting does
correctly account for dirs with ".." components.)
under the RETURN VALUES section so it is consistent with others.
Cleanup the return value text for getenv(3) a little while I am here.

{ip,udp,tcp} header and return a void * pointing to the payload (i.e. the
first byte past the end of the header and any required padding). Use them
consistently throughout libalias to a) reduce code duplication, b) improve
code legibility, c) get rid of a bunch of alignment warnings.
a short pointer. The previous implementation seems to be in a gray zone
of the C standard, and GCC generates incorrect code for it at -O2 or
higher on some platforms.
These trivial implementations are about 25 times slower than
rint{,f}() on x86 due to the FP environment save/restore.
They should eventually be redone in terms of fegetround() and
bit fiddling.
named link, foo_link or link_foo to lnk, foo_lnk or lnk_foo, fixing
signed / unsigned comparisons, and shoving unused function arguments
under the carpet.
I was hoping WARNS?=6 might reveal more serious problems, and perhaps
the source of the -O2 breakage, but found no smoking gun.
