[Mingw-w64-public] winpthreads: declaration of pid_t and autoconf's AC_TYPE_PID_T

I think it is worth to report this issue to autoconf-bug mailing list first. I'll do it. If they will not want to fix this, we can simply ``` #ifdef pid_t #undef pid_t #endif ``` since we typedef it to the same base type as AC_TYPE_PID_T #define's it. - Kirill Makurin

[Mingw-w64-public] winpthreads: add a pkg-config file?

Now that winpthreads can be built with MSVC, I think it is usable as a package on its own. Having a pkg-config file would make using winpthreads much easier with meson and cmake. For instance, with meson one could ``` If host_machine.system() == 'windows' threads = dependency('winpthreads') els

Re: [Mingw-w64-public] Inconsistent behavior of btowc with "C" locale

Initially it was a simple patch to make `btowc` and `wctob` match UCRT behavior. If do serious changes to `btowc` and `wctob`, I think we should also take a look at `mb*towc*` and `wc*tomb*` functions provided by mingw-w64. I do not say and I do not think that we should replace `mb*towc*` and `

[Mingw-w64-public] widl build error on Cygwin

I just tried to build llvm-mingw on Cygwin, as part of testing builds of llvm/clang/lld on Cygwin, and got a new error building widl: In file included from /usr/include/limits.h:13, from /usr/lib/gcc/x86_64-pc-cygwin/12/include/limits.h:203, from /usr/lib/gcc/x86_

[Mingw-w64-public] [PATCH 09/10] crt: Define LFS open64, freopen64, tmpfile64 symbols as aliases in crt-aliases.def.in

All these functions with suffix 64 are specified in the Large File Specification. mingw-w64 does not need anything special for them, every opened file on Windows can be used with 64-bit offset support. --- mingw-w64-crt/def-include/crt-aliases.def.in | 3 +++ mingw-w64-crt/lib-common/

Function _lseeki64() is available since msvcrt40.dll. For older CRT libraries provides emulation via lseek(). --- mingw-w64-crt/Makefile.am | 1 + mingw-w64-crt/stdio/_lseeki64.c | 22 ++ 2 files changed, 23 insertions(+) create mode 100644 mingw-w64-crt/stdio/_lseeki64

[Mingw-w64-public] [PATCH 05/10] crt: Define ftello64 symbol as alias to _ftelli64

mingw-w64 implementation of ftello64() and _ftelli64() functions are same. So remove the ftello64 implementation and define ftello64 symbol as an alias to the _ftelli64 symbol. This change allows to use native msvcr80+ / UCRT implementation of _ftelli64() function for the POSIX ftello64() instead

[Mingw-w64-public] [PATCH 10/10] headers: Deinline UCRT fseeko(), fseeko64(), ftello() and ftello64() functions

All those UCRT inline functions are defined just as redirects to another functions. All those functions have already defined symbols in UCRT import library (as aliases). So remove inline functions and unify them between msvcrt and UCRT builds. Add missing __cdecl and _CRTIMP keywords. --- mingw-w6

[Mingw-w64-public] [PATCH 02/10] crt: Define fseeko and ftello symbols as aliases to fseek and ftell

Both msvcrt and UCRT ABI uses for off_t-based function without any suffix in their name the 32-bit long off_t type for both 32-bit and 64-bit architectures. So define the fseeko symbol as alias to fseek and ftello symbol as alias to ftell symbol because the fseek and ftell also uses only 32-bit of
