Change subject: use reasonable value if PATH_MAX is not defined
......................................................................


Patch Set 1:

Actually,  I think this ultimately belongs into autoconf:

# Some Unix systems, like Gnu Hurd, don't define PATH_MAX
AC_MSG_CHECKING([for PATH_MAX])
AC_COMPILE_IFELSE( [AC_LANG_PROGRAM([[#include <limits.h>]],
                                    [[char dummy[PATH_MAX];]])],
                   [
                      AC_MSG_RESULT([yes])
                      AC_DEFINE_UNQUOTED([HAVE_PATH_MAX], 1, [Define to 1 if you have the PATH_MAX macro.])
                    ],
                    [
                      AC_MSG_RESULT([no])
                      AC_DEFINE_UNQUOTED([HAVE_PATH_MAX], 0, [Define to 1 if you have the PATH_MAX macro.])
                    ]
                 )

and then we can have (in a shared header)

#if HAVE_PATH_MAX=0
#define PATH_MAX 4096
#endif
