I have fixed it mostly as you suggest, but prepending an underscore as
suggested by gnulib[1]. Hello, just searched mkdir in mingw/include: ```
mingw/include $ grep -r -nH mkdir * direct.h:34: _CRTIMP int __cdecl
_mkdir(const char *_Path); direct.h:55: _CRTIMP int __cdecl _wmkdir(const
wchar_t *_Path); direct.h:65: int __cdecl mkdir(const char *_Path)
__MINGW_ATTRIB_DEPRECATED_MSVC2005; io.h:282: int __cdecl mkdir (const char
*) __MINGW_ATTRIB_DEPRECATED_MSVC2005; tchar.h:326:#define _tmkdir _wmkdir
tchar.h:650:#define _tmkdir _mkdir wchar.h:299: _CRTIMP int __cdecl
_wmkdir(const wchar_t *_Path); ``` It's the same for mingw-gcc v5, v8,
v12. Thread: [Mingw-w64-public] mkdir and MINGW_ATTRIB_DEPRECATED_MSVC2005

Win32 mkdir vs _mkdir stackoverflow.com
stackoverflow.com/questions/33326732/win32-mkdir-vs-mkdir "Only the old
name is deprecated, not the function, and only in Visual Studio, not in POSIX.
Basically, the reason is that mkdir isn't defined as a runtime library
function in the ISO C++ standard, and non-standard runtime library functions
are expected to begin with an underscore." And it, indeed is not covered
by C standard _mkdir is microsoft thing: learn.microsoft.com
learn.microsoft.com/en-us/cpp/c-runtime-library/reference/mkdir "The
Microsoft-implemented POSIX function name mkdir is a deprecated alias for the
_mkdir function. By default, it generates Compiler warning (level 3) C4996. The
name is deprecated because it doesn't follow the Standard C rules for
implementation-specific names. However, the function is still supported. We
recommend you use _mkdir instead. Or, you can continue to use this function
name, and disable the warning. For more information, see Turn off the warning
and POSIX function names." I don't know the stand of mingw of other
compiler developers, what is and what is not standard/non standard, deprecated
or not, but I, personally, would use mkdir, just because it does not compile on
MSVC. I mean, last time I tested it compiled but did not work - it produced
corrupetd bitstream somewhere on the way. But that's my opinion. If Gnulib
says to use underscore I get that. You'll have to add `#include
<direct.h>' along with `<io.h>' otherwise you get:
`implicit declaration of function '_mkdir''. ``` main.c: In
function 'make_dirs': main.c:45:26: warning: implicit declaration of
function '_mkdir'; did you mean 'mkdir'?
[-Wimplicit-function-declaration] #define mkdir(name,mode) _mkdir(name)
^~~~~~ ``` en.wikipedia.org
en.wikipedia.org/wiki/Direct.h You should definitely get your own mingw copy
to test that as well. I use it through wine, with msys. I have old msys-1,
which is bash with posix tools, and as it does not introduce its own
dependencies. ( mediafire.com
mediafire.com/file/xwn8jh9l908u7rn/msys-1.10.zip/file ) Fill
$MSYS_DIR/etc/fstab as in example/s and: ``` $ cd $MSYS_DIR $ wine cmd.exe
z:\msys> msys_mintty.bat # or msys_sh.bat z:\msys> gcc -v ```
