dnl @synopsis AC_FUNC_MKDIR
dnl
dnl Check whether mkdir() is mkdir or _mkdir, and whether it takes one or two
dnl arguments.
dnl
dnl This macro can define HAVE_MKDIR, HAVE__MKDIR, and MKDIR_TAKES_ONE_ARG,
dnl which are expected to be used as follow:
dnl
dnl #if HAVE_MKDIR
dnl # if MKDIR_TAKES_ONE_ARG
dnl /* Mingw32 */
dnl # define mkdir(a,b) mkdir(a)
dnl # endif
dnl #else
dnl # if HAVE__MKDIR
dnl /* plain Win32 */
dnl # define mkdir(a,b) _mkdir(a)
dnl # else
dnl # error "Don't know how to create a directory on this system."
dnl # endif
dnl #endif
dnl
dnl @version $Id$

dnl Note:
dnl =====
dnl I have not implemented the following suggestion because I don't have
dnl access to such a broken environment to test the macro. So I'm just
dnl appending the comments here in case you have, and want to fix
dnl AC_FUNC_MKDIR that way.

dnl |Thomas E. Dickey (dickey@herndon4.his.com) said:
dnl | it doesn't cover the problem areas (compilers that mistreat mkdir
dnl | may prototype it in dir.h and dirent.h, for instance).
dnl |
dnl |Alexandre:
dnl | Would it be sufficient to check for these headers and #include
dnl | them in the AC_TRY_COMPILE block? (and is AC_HEADER_DIRENT
dnl | suitable for this?)
dnl |
dnl |Thomas:
dnl | I think that might be a good starting point (with the set of recommended
dnl | ifdef's and includes for AC_HEADER_DIRENT, of course).
