dnl Check whether mkdir() is mkdir or _mkdir, and whether it takes one

dnl or two arguments.

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

dnl
|

dnl #if HAVE_MKDIR

dnl # if MKDIR_TAKES_ONE_ARG
|

dnl /* MinGW32 */

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).
