[Mingw-w64-public] [PATCH 1/4] crt: Check for underflow in *stat32i64 functions

msvcrt *stat32* functions do not work for time before year 1970. Add similar underflow checks into mingw-w64 emulations. --- mingw-w64-crt/stdio/_fstat32i64.c | 6 +++--- mingw-w64-crt/stdio/_stat32i64.c | 6 +++--- mingw-w64-crt/stdio/_wstat32i64.c | 6 +++--- 3 files changed, 9 insertions(+), 9

[Mingw-w64-public] [PATCH 2/4] crt: Provide emulation of _fstat32, _stat32 and _wstat32 functions for 64-bit msvcrt builds

All 64-bit CRT libraries except the msvcrt.dll provides native _fstat32, _stat32 and _wstat32 functions. 64-bit system os msvcrt.dll is an exception and does not contain these function. So implement mingw-w64 emulation of these functions via the 64-bit variants of stat functions. Reported issue: h

[Mingw-w64-public] [PATCH 0/3] crt: Improve LFS 64-bit functions (part 2)

Additional changes for "crt: Improve LFS 64-bit functions" series. Should be applied on top of them. Pali Rohár (3): headers: Add missing __cdecl for fopen64() function headers: Declare missing open64(), freopen64() and tmpfile64() functions crt: Add testcases for lfs functions mingw-w

[Mingw-w64-public] [PATCH] crt: Fix compilation of libscrnsavw.a

Setting the lib32_libscrnsavw_a_CFLAGS variable automatically turns off usage of AM_CFLAGS variable for that target. As the AM_CFLAGS contains the mingw-w64 CRT build flags, specify it manually in lib32_libscrnsavw_a_CFLAGS variable. Do same for all architectures. --- mingw-w64-crt/Makefile.am | 8

[Mingw-w64-public] [PATCH 0/4] crt: Fix _*stat32 and _*stat32i64 functions for 64-bit msvcrt.dll builds

This patch series adds _fstat32, _stat32, _wstat32, _fstat32i64, _stat32i64 and _wstat32i64 function emulation for 64-bit msvcrt.dll builds as the msvcrt.dll is missing those functions. Last change adds a compile time test which ensures that all _fstat*, _stat* and _wstat* functions can be used in

[Mingw-w64-public] [PATCH] crt: Fix running "make check" testsuite

AM_CFLAGS contains cflags required to build the mingw-w64 CRT source code. They are not intended to compile applications (including those used in mingw-w64 testsuite). Setting per-target _CFLAGS variable overwrites the AM_CFLAGS. So for every testcase sets the custom _CFLAGS variable. This ensures
