Fix make_relative_path() to support cases where target_path and bin_path

that they match up to the last component, accept whatever common prefix
they have, and try to replace the non-matching part of bin_path with
the non-matching part of target_path in the actual executable's path.

a match to the part of bin_path we want to substitute for, rather than
blindly stripping one directory component from the executable's path.

Adjust string comparison so that only bitwise-equal strings are considered
equal: if strcoll claims two strings are equal, check it with strcmp, and
sort according to strcmp if not identical. This fixes inconsistent

as well. Also, take advantage of the now-well-defined behavior to speed up

there's a paragraph in the ALTER TABLE reference page that reads:
DROP CONSTRAINT
This form drops constraints on a table. Currently, constraints on tables
are not required to have unique names, so there may be more than one
constraint matching the specified name. All matching constraints will be
dropped.
To my knowledge, it is no longer possible to create constraints with the
same name for the same relation. When you create a constraint and specify
the same name explictly, an error is raised. Implicit constraint creation
won't choose an existing name either and up to now you could not rename a
constraint. Renaming works with the patch I sent in a few hours ago but this
patch as well won't allow constraints with identical names on the same
relation.

Disble some Win32-specific code in win32-client-only builds:
I have the problem, when building by MS-VC6.
An error occurs in the 8.1.0 present source codes.
nmake -f win32.mak
..\..\port\getaddrinfo.c(244) : error C2065: 'WSA_NOT_ENOUGH_MEMORY'
..\..\port\getaddrinfo.c(342) : error C2065: 'WSATYPE_NOT_FOUND'
This is used by winsock2.h. However, Construction of a windows base is
winsock.h.
Then, Since MinGW has special environment, this is right. but, it is not
found in VC6.
Furthermore, in getaddrinfo.c, IPV6-API is used by
LoadLibraryA("ws2_32");
Referring to of dll the external memory generates this violation by VC6
specification.
I considered whether the whole should have been converted into winsock2.
However, Now, DLL of MinGW creation operates wonderfully as it is.
That's right, it has pliability by replacement of simple DLL.
Then, I propose the system using winsock(non IPV6) in construction of
VC6.

Push the responsibility for handling ignore_killed_tuples down into
_bt_checkkeys(), instead of checking it in the top-level nbtree.c routines
as formerly. This saves a little bit of loop overhead, but more importantly
it lets us skip performing the index key comparisons for dead tuples.

A couple of tiny performance hacks in _bt_step(). Remove PageIsEmpty
checks, which were once needed because PageGetMaxOffsetNumber would
fail on empty pages, but are now just redundant. Also, don't set up
local variables that aren't needed in the fast path --- most of the
time, we only need to advance offnum and not step across a page boundary.
Motivated by noticing _bt_step at the top of OProfile profile for a
pgbench run.
