* kb/msvc-compile:
Windows: do not redefine _WIN32_WINNT
MinGW: Fix stat definitions to work with MinGW runtime version 4.0
MSVC: fix stat definition hell
MSVC: fix compile errors due to macro redefinitions
MSVC: fix compile errors due to missing libintl.h
In msvc.h, there's a couple of stat related functions defined diffently
from mingw.h. When we remove these definitions, the only problem we get is
"warning C4005: '_stati64' : macro redefinition" for this line in mingw.h:
#define _stati64(x,y) mingw_stat(x,y)
The reason is that as of MSVCR80.dll (distributed with MSVC 2005), the
original _stati64 family of functions was renamed to _stat32i64, and the
former function names became macros (pointing to the appropriate function
based on the definition of _USE_32BIT_TIME_T).
Defining _stati64 works on MinGW because MinGW by default compiles against
the MSVCRT.DLL that is part of Windows (i.e. _stati64 is a function rather
than a macro).
Note: MinGW *can* compile for newer MSVC runtime versions, and MSVC
apparently can also compile for the Windows MSVCRT.DLL via the DDK (see
http://www.syndicateofideas.com/posts/fighting-the-msvcrt-dll-hell ).
Remove the stat definitions from msvc.h, as they are not compiler related.
In mingw.h, determine the runtime version in use from the definitions of
_stati64 and _USE_32BIT_TIME_T, and define stat() accordingly.
This also fixes that stat() in MSVC builds still resolves to mingw_lstat()
instead of mingw_stat().

Sparse issues 68 errors (two errors for each main() function) such
as the following:
SP git.c
git.c:510:5: error: too many arguments for function mingw_main
git.c:510:5: error: symbol 'mingw_main' redeclared with different type \
(originally declared at git.c:510) - different argument counts
The errors are caused by the 'main' macro used by the MinGW build
to provide a replacement main() function. The original main function
is effectively renamed to 'mingw_main' and is called from the new
main function. The replacement main is used to execute certain actions
common to all git programs on MinGW (e.g. ensure the standard I/O
streams are in binary mode).
In order to suppress the errors, we change the macro to include the
parameters in the declaration of the mingw_main function.
Unfortunately, this change provokes both sparse and gcc to complain
about 9 calls to mingw_main(), such as the following:
CC git.o
git.c: In function 'main':
git.c:510: warning: passing argument 2 of 'mingw_main' from \
incompatible pointer type
git.c:510: note: expected 'const char **' but argument is of \
type 'char **'
In order to suppress these warnings, since both of the main
functions need to be declared with the same prototype, we
change the declaration of the 9 main functions, thus:
int main(int argc, char **argv)

Should it be static?
compat/mingw.c:1207:23: warning: Using plain integer as NULL pointer
In 'pinfo_t' variable, defined on line 795, seems to have been a
mistake (a missing typedef keyword?), so we simply remove it.
The 'pinfo' variable does not require more than file scope, so we
simply add the static modifier to the declaration.
The 'pinfo_cs' variable, in contrast, requires initialisation in the
mingw replacement main() function, so we add an extern declaration to
the compat/mingw.h header file.
The remaining warning is suppressed by replacing the rhs of the
pointer assignment with the NULL pointer literal.

spurious "Invalid argument" errors on Windows when a pipe was broken. But
this check may hide real errors on systems that do not have the this odd

The current t9300-fast-import.sh test number 62 ("L: nested tree
copy does not corrupt deltas") was introduced in commit 9a0edb79
("fast-import: add a test for tree delta base corruption",
15-08-2011). A fix for the demonstrated problem was introduced
by commit 8fb3ad76 ("fast-import: prevent producing bad delta",
15-08-2011). However, this fix didn't work on MinGW and so this
test has always failed on MinGW.
Part of the solution in commit 8fb3ad76 was to add an NO_DELTA
preprocessor constant which was defined as follows:
+/*
+ * We abuse the setuid bit on directories to mean "do not delta".
+ */
+#define NO_DELTA S_ISUID
+
Unfortunately, the S_ISUID constant on MinGW is defined as zero.
In order to fix the problem, we simply alter the definition of
S_ISUID in the mingw header file to a more appropriate value.
Also, we take the opportunity to similarly define S_ISGID and
S_ISVTX.

The POSIX standard specifies a return type of int for all six exec
functions. In addition, all exec functions return -1 on error, and
simply do not return on success. However, the current emulation of
the exec functions on mingw are declared with a void return type.
This would cause a problem should any code attempt to call the
exec function in a non-void context. In particular, if an exec
function were used in a conditional it would fail to compile.
In order to improve the fidelity of the emulation, we change the
return type of the mingw_execv[p] functions to int and return -1
on error.

The mingw-runtime implemenation of opendir, readdir and closedir
sets errno to 0 on success, something that POSIX explicitly
forbids. 3ba7a06 ("A loose object is not corrupt if it cannot be
read due to EMFILE") introduce a dependency on this behaviour,
leading to a broken "git clone" on Windows.
compat/mingw.c contains an implementation of readdir, and
compat/msvc.c contains implementations of opendir and closedir.
Move these to compat/win32/dirent.[ch], and change to our own DIR
structure at the same time.
This provides a generic Win32-implementation of opendir, readdir
and closedir which works on both MinGW and MSVC and does not reset
errno, and as a result git clone is working again on Windows.

The Windows port have so far been using process handles in place
of PID. However, this is not work consistent with what getpid
returns.
PIDs are system-global identifiers, but process handles are local
to a process. Using PIDs instead of process handles allows, for
instance, a user to kill a hung process with the Task Manager,
something that would have been impossible with process handles.
Change the code to use the real PID, and use OpenProcess to get a
process-handle. Store the PID and the process handle in a linked
list protected by a critical section, so we can safely close the
process handle later.

most git commands. (msysGit issue #445)

Bigger writes to network drives on Windows XP fail. Cap them at 31MB to

that do less work than requested anyway.
On local drives, write() calls are translated to WriteFile() calls with
a cap of 64KB on Windows XP and 256KB on Vista. Thus a cap of 31MB won't
affect the number of WriteFile() calls which do the actual work. There's
