Commit 4091bfc (MinGW: Add missing file mode bit defines,
28-12-2009) causes the msvc build to issue many additional
(currently 1008) macro redefinition warnings. The warnings
relate to the S_IRUSR, S_IWUSR, S_IXUSR and S_IRWXU macros.
In order to fix the warnings, we simply remove the offending
macro definitions which, for both msvc and MinGW, are not
required.

Commit c03c831 (do not depend on signed integer overflow,
05-10-2010) provokes an msvc build failure. The cause of the
failure is a missing definition of the INTMAX_MAX constant,
used in the new maximum_signed_value_of_type(a) macro, which
would normally be defined in the C99 <stdint.h> header file.
In order the fix the compilation error, we add an appropriate
definition of the INTMAX_MAX constant, along with INTMAX_MIN
and UINTMAX_MAX, to an msvc compat header file.

The msvc winsock2.h header file conditionally defines or declares
poll() related symbols which cause many macro redefinition errors,
a struct type redefinition error and syntax errors. These symbols
are defined in support of the WSAPoll() API, new in Windows Vista,
when the symbol _WIN32_WINNT is defined and _WIN32_WINNT >= 0x0600.
In order to avoid the compilation errors, we set _WIN32_WINNT to
0x0502 (which would target Windows Server 2003) prior to including
the winsock2.h header file.

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.

compat/mingw.c's readdir expects to be the one that starts the search,

Fix this by removing the call to _findfirst, and initializing dd_handle

At the same time, make sure we use FindClose instead of _findclose,
which is symmetric to readdir's FindFirstFile. Take into account that
the find-handle might already be closed by readdir.

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.

compat/regexec.c had a weird combination of function declaration in ANSI
style and function definition in K&R style, for example:
static unsigned
re_copy_regs (struct re_registers *regs, regmatch_t *pmatch,
int nregs, int regs_allocated) internal_function;
static unsigned
re_copy_regs (regs, pmatch, nregs, regs_allocated)
struct re_registers *regs;
regmatch_t *pmatch;
int nregs, regs_allocated;
{ ... }
with this #define:
#ifndef _LIBC
# ifdef __i386__
# define internal_function __attribute ((regparm (3), stdcall))
# else
# define internal_function
# endif
#endif
The original version as shown above was fine, but with the ANSIfied
function definition and in the case where internal_function is not empty,
gcc identifies the declaration and definition as different and bails out.
Adding internal_function to the definition doesn't help (it results in
a syntax error); hence, remove it from the subset of declarations that gcc
flags as erroneous.

Bigger writes to network drives on Windows XP fail. Cap them at 31MB to
allow them to succeed. Callers need to be prepared for write() calls
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
