Further refactoring of c.h and nearby files.
This continues the work of commit 91aec93e6 by getting rid of a lot of
Windows-specific funny business in "section 0". Instead of including
pg_config_os.h in different places depending on platform, let's
standardize on putting it before the system headers, and in consequence
reduce win32.h to just what has to appear before the system headers or
the body of c.h (the latter category seems to include only PGDLLIMPORT
and PGDLLEXPORT). The rest of what was in win32.h is moved to a new
sub-include of port.h, win32_port.h. Some of what was in port.h seems
to better belong there too.
It's possible that I missed some declaration ordering dependency that
needs to be preserved, but hopefully the buildfarm will find that
out in short order.
Unlike the previous commit, no back-patch, since this is just cleanup
not a prerequisite for a bug fix.

|
||||
* NT_ERROR 0xC0000000 - 0xFFFFFFFF
|
||||
*
|
||||
* Effectively, we don't care on the severity of the return value from
|
||||
* system(), we just need to know if it was because of exit() or generated
|
||||
* by the system, and it seems values >= 0x100 are system-generated.
|
||||
* See this URL for a list of WIN32 STATUS_* values:
|
||||
*
|
||||
* Wine (URL used in our error messages) -
|
||||
* http://source.winehq.org/source/include/ntstatus.h
|
||||
* Descriptions - http://www.comp.nus.edu.sg/~wuyongzh/my_doc/ntstatus.txt
|
||||
* MS SDK - http://www.nologs.com/ntstatus.html
|
||||
*
|
||||
* It seems the exception lists are in both ntstatus.h and winnt.h, but
|
||||
* ntstatus.h has a more comprehensive list, and it only contains
|
||||
* exception values, rather than winnt, which contains lots of other
|
||||
* things:
|
||||
*
|
||||
* http://www.microsoft.com/msj/0197/exception/exception.aspx
|
||||
*
|
||||
* The ExceptionCode parameter is the number that the operating system
|
||||
* assigned to the exception. You can see a list of various exception codes
|
||||
* in WINNT.H by searching for #defines that start with "STATUS_". For
|
||||
* example, the code for the all-too-familiar STATUS_ACCESS_VIOLATION is
|
||||
* 0xC0000005. A more complete set of exception codes can be found in
|
||||
* NTSTATUS.H from the Windows NT DDK.
|
||||
*
|
||||
* Some day we might want to print descriptions for the most common
|
||||
* exceptions, rather than printing an include file name. We could use
|
||||
* RtlNtStatusToDosError() and pass to FormatMessage(), which can print
|
||||
* the text of error values, but MinGW does not support
|

* RtlNtStatusToDosError().
