Documentation

Check whether mkdir() is mkdir or _mkdir, and whether it takes one or two arguments.

This macro can define HAVE_MKDIR, HAVE__MKDIR, and MKDIR_TAKES_ONE_ARG, which are expected to be used as follows:

 #if HAVE_MKDIR
 #  if MKDIR_TAKES_ONE_ARG
      /* MinGW32 */
 #    define mkdir(a, b) mkdir(a)
 #  endif
 #else
 #  if HAVE__MKDIR
      /* plain Windows 32 */
 #    define mkdir(a, b) _mkdir(a)
 #  else
 #    error "Don't know how to create a directory on this system."
 #  endif
 #endif

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).
