In mkdir.c in libgnu, I found the following,

int
rpl_mkdir (char const *dir, mode_t mode maybe_unused)
{

So I carried out 'grep' in the source directories. I found the following in 
gnulib/lib/sys_stat.in.h

/* Before doing "#define mkdir rpl_mkdir" below, we need to include all
   headers that may declare mkdir().  */
#if (defined _WIN32 || defined __WIN32__) && ! defined __CYGWIN__
# include <io.h>
#endif

In io.h in MinGW, 

_CRTIMP int __cdecl __MINGW_NOTHROW _mkdir (const char*);

However in file_ops.h in liboctave, I found the following.

  static int mkdir (const std::string&, mode_t);
  static int mkdir (const std::string&, mode_t, std::string&);

Perhaps some treatment is required for mkdir for MinGW build.

Any suggestions?
