We are building libiconv now the same way as upstream MinGW does, so we do
not need OLD_ICONV anymore when compiling Git either in msysGit or
mingwGitDevEnv.

Due to a bug in the Darwin kernel, write(2) calls have a maximum size
of INT_MAX bytes.

Introduce a new compat function, clipped_write(), that only writes
at most INT_MAX bytes and returns the number of bytes written, as
a substitute for write(2), and allow platforms that need this to
enable it from the build mechanism with NEEDS_CLIPPED_WRITE.

Set it for Mac OS X by default.  It may be necessary to include this
function on Windows, too.

If you try this:

 1. Install Git for Windows (from the msysgit project)

 2. Put

	[core]
		autocrlf = false
		eol = native

    in your .gitconfig.

 3. Clone a project with

	*.txt text

    in its .gitattributes.

Then with current git, any text files checked out have LF line
endings, instead of the expected CRLF.

This reverts commit 78457bc0.

commit 28c5d9ed ("vcs-svn: drop string_pool") previously removed
the only call-site for strtok_r. So let's get rid of the compat
implementation as well.

Commit 2f769195 ("MinGW: avoid collisions between "tags" and "TAGS",
28-09-2010) enabled MinGW to use an ETAGS file in order to avoid
filename collisions on (Windows) case insensitive filesystems. In
addition, this prevents 'make' from issuing several warning messages.

When using the Makefile to perform an MSVC build, which is usually
executed using MinGW tools, we can also benefit from this capability.
In order to reap the above benefits, we set the ETAGS_TARGET build
variable to ETAGS in the MSVC config block.

In particular, while linking test-svn-fe.exe, the linker complains
that the external symbol _strtoull is unresolved. A call to this
function was added in commit ddcc8c5b ("vcs-svn: skeleton of an svn
delta parser", 25-12-2010).

The NO_STRTOULL build variable attempts to provide support to old
systems which can't even declare 'unsigned long long' variables,
let alone provide the strtoll() or strtoull() functions. Setting
this build variable does not provide an implementation of these
functions. Rather, it simply allows the compat implementations
of strto{i,u}max() to use strtol() and strtoul() instead.

In order to fix the linker error on systems with NO_STRTOULL set,
currently MSVC and OSF1, we can substitute a call to strtoumax().

However, we can easily provide support for the strtoull() and
strtoll() functions on MSVC, since they are essentially already
available as _strtoui64() and _strtoi64(). This allows us to
remove NO_STRTOULL for MSVC.

In particular, while linking git-daemon.exe, the linker complains
that the external symbols _inet_pton and _inet_ntop are unresolved.
Commit a666b472 ("daemon: opt-out on features that require posix",
04-11-2010) addressed this problem for MinGW by configuring the
use of the internal 'compat' versions of these function.

Although the MSVC header <WS2tcpip.h> contains the prototypes for
the inet_pton and inet_ntop functions, they are only visible for
Windows API versions from 0x0600 (Windows Vista) or later. (In
addition, on Windows XP, ws2_32.dll does not export these symbols).

In order to fix the linker errors, we also configure the MSVC build
to use the internal compat versions of these functions by setting
the NO_INET_{PTON,NTOP} build variables.

former on systems that define the EXPAT_NEEDS_XMLPARSE_H variable and

Our Makefile first sets up some sane per-platform defaults
by looking at "uname", then modifies that according to the
results of autoconf (if any), then modifies that according
to the user's wishes in config.mak.

For sub-Makefiles like Documentation/Makefile, the latter
two are available, but the uname defaults are available only
to the main Makefile. This hasn't been a problem so far,
because the sub-Makefiles do not rely on any of those
automatic settings to do their work.

This patch puts the uname magic into its own file so it can
be reused in other Makefiles, opening up the possibility of
new knobs.

Note that we leave one reference to uname in the top-level
Makefile: if we are on Darwin, we must check the NO_FINK and
NO_DARWIN_PORTS settings. But because we are combining uname
settings with user-options, we must do so after all of the
config is loaded. This is acceptable, as the resulting
conditionals are about setting variables specific to the
top-level Makefile (and if that ever changes, we can hoist
them into a separate post-config include, too).
