well as the few userland tools which were only used on these platforms.

There has not been enough activity and interest towards these platform
to keep them lying in the tree.

icmp protocol naming particularly with pfctl, since the manpage is
icmp6(4) (not ipv6-icmp(4)).

we don't want any user defines to change how the inlined ctype
functions behave.

not EOF is defined to determine if stdio.h has been included.
Instead, use __EOF which should be OK wrt namespace safety.

o Add __BEGIN_DECLS/__END_DECLS to include files
o Safe macros
o Remove useless variable assignment in the End function of *hl.c
o Some minor KNF, needs more

pval@ millert@ ok.

sparc64.  Change cast back to unsigned char but do a bitwise AND
with 0xff to avoid any sign extension weirdness and to make it
impossible for us to overflow _C_ctype_.  The bitwise AND is probably
not needed and may be removed later if this does not trigger compiler bugs.

instead to make these one-liners.  Works around a compiler bug on vax
that affects both the libc and inline versions identically.

Remove useless check for EOF in isascii

int, not a char.

currently have with the macro versions and makes the ctype.h versions
100% identical to what is in libc.
Discussed with pjanzen@ and OK'd by deraadt@.

code that assign a u_int value to x_handy.  However, this means
that we need to be careful checking for overflow as we can no longer
subtract a value and check the result for < 0.  We reorder the
expression instead to avoid this problem (basic algebra).
deraadt@ OK

it is not the fist character of optstring (since that would conflict
with GNU semantics).
Update the bit on "W;" within optstring when called as getopt (not
getopt_long) to current reality.

in optstring.  Problem noticed by Theo.

of optstring to avoid a semantic conflict with GNU getopt.

return -1 like POSIX requires.

This is used by a few programs such as man and su.
