The stdio functions are typically provided by the language provider on
windows. So when you build with Microsoft Visual C++, you're using the "CRT"
or C run-time they provided. This is also related to why you can't pass
file* streams. Other systems (borland, cygwin, etc) will have different
implementations.

It does look like direct.h (as mentioned in someone else's reply) contains a
version of mkdir, though it doesn't have support for the mode; that would be
easy to workaround (just don't pass it, or define a macro or function to
remove it.).

So my current version is as follows; I don't have time to do any more with
this, or check if errno is set, but it makes things quite a bit cleaner

1) after the malloc, still set dirbuild[0] = '\0'; otherwise leave
create_dir_hierarchy alone.

2) somewhere (I stuck it in the #ifdef WIN32 at the top of the file, you may
want to put it elsewhere, and only for VC6), add the following:

#ifdef whatever-the-right-thing-is
#include <direct.h>
#define F_OK 0
// you might want to split this into declaration/definition, i just threw it
in main.c and thus didn't care.
// you might to use better name than mkdirWIN32hack. maybe mkdirNoMode
int mkdirWIN32hack(const char * sz, int mode)
{
    return mkdir(sz);
}
#define mkdir mkdirWIN32hack
#define mode_t int
#endif
