Hello,
The following patch is for release 2.75 and the CVS version of autoconf.
The patch addresses two issues in m4sugar/m4sh.m4:
1) _AS_MKDIR_P_PREPARE behaves incorrectly on some platforms (such as
NextStep and OpenStep) for which `mkdir' does not recognize any options. The
existing implementation leaves a bogus directory named "-p" sitting in the
working directory. The patch removes this bogus directory if present.
2) _AS_MKDIR_P_PREPARE neglects to take advantage of the older `mkdirs'
command (note the plural) which exists on some platforms (such as NextStep
and OpenStep), and which performs the same functions as `mkdir -p'. The
patch adds a check for `mkdirs' if `mkdir -p' fails.
