Mingw-w64 commit id 850703ae46e1971c5789fa1bdd802fb9692c41c9 by Daniel Starke via Mingw-w64-public <[email protected]>
headers: Change _S_IFBLK from 0x3000 to 0x6000
The _S_IFBLK macro, used to identify block special files in file systems, is
being updated from 0x3000 to 0x6000. This change aligns mingw-w64 with the more
commonly used value across Unix-like systems and other C libraries.
The old value of 0x3000 may have caused compatibility issues when working with
code that assumes the standard 0x6000 value for S_IFBLK.
This update improves cross-platform compatibility and consistency with other
systems, making it easier to write portable code that deals with file type
identification. It also reduces potential confusion and errors that might arise
from the non-standard value.
One of these is for example python. This is only an example. It does not change
the fact that python should be more careful about actual value implementation.
Note that the current value implies character device + FIFO instead of
character device + directory.

#pragma function(llabs) causes an error: "error: no_builtin attribute has no effect on defaulted or deleted functions"
This is probably a bug in clang, see https://github.com/llvm/llvm-project/issues/116256
These headers come with the MS compiler. Some of them are standard, like emmintrin.h, others are MS specific like crtdefs.h
This separation will allow using MS CRT headers. Eventually it can allow compiling with the compilers' runtime headers.
- Use _alloca instead of non-standard alloca
- Use _TCHAR instead of non-standard TCHAR
- Use _off_t instead of deprecated off_t
- Use _O_BINARY instead of O_BINARY
This is already done this way in our stdlib.h. It is needed by GCC 13 C++ headers. The problem happens like this:
- telnet/precomp.h includes fstream from GCC
- fstream includes pthread.h from GCC
- pthread.h includes process.h from ReactOS
- process.h defines _CRT_TERMINATE_DEFINED, but doesn't declare _Exit
- fstream includes cstdlib from GCC
- cstdlib includes stdlib.h from GCC (#include_next)
- stdlib.h doesn't declare _Exit, because _CRT_TERMINATE_DEFINED is defined
- cstdlib uses _Exit
Use the MS PSDK-compatible name _INC_MALLOC, instead of the MinGW one
_MALLOC_H_, so that code that may depend on this to determine whether
malloc.h functions are defined, can compile without problems.
- Add some missing ARM64 exports to ntdll, kernel32 and user32
- Create mmtypes header file based on WoA debug symbols
- Get the remaining headers in order, so we can build ARM64 apps
- Adjust subsystem version for binaries so they can run on WoA host
- Get calc, notepad and more base apps to build for ARM64 platform

A little bug were in the CRT, found with RosBE and cegcc compiler:
../sdk/include/crt/mingw32/intrin_arm.h:44:32: error: '<<' in boolean context, did you mean '<' ? [-Werror=int-in-bool-context]
Thanks to @HBelusca for suggesting the fix. CORE-17604
