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 follow:
# if MKDIR_TAKES_ONE_ARG
/* Mingw32 */
# define mkdir(a,b) mkdir(a)
# if HAVE__MKDIR
/* plain Win32 */
# define mkdir(a,b) _mkdir(a)
# error "Don't know how to create a directory on this system."
AC_DEFUN([AC_FUNC_MKDIR], [AC_CHECK_FUNCS([mkdir _mkdir]) AC_CACHE_CHECK([whether mkdir takes one argument], [ac_cv_mkdir_takes_one_arg], [AC_TRY_COMPILE([ #include <sys/stat.h> #if HAVE_UNISTD_H # include <unistd.h> #endif ],[mkdir (".");], [ac_cv_mkdir_takes_one_arg=yes],[ac_cv_mkdir_takes_one_arg=no])]) if test x"$ac_cv_mkdir_takes_one_arg" = xyes; then AC_DEFINE([MKDIR_TAKES_ONE_ARG],1, [Define if mkdir takes only one argument.]) fi ]) 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 dnl |Thomas E. Dickey (email@example.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).
