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 |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).
