# ===========================================================================
#
# SYNOPSIS
#
# AX_FUNC_MKDIR
#
# DESCRIPTION
#
# 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 AX_FUNC_MKDIR that way.
dnl
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).
