[PATCH 7/10] Fix header breakage due to redefining PATH_MAX.

The header builtin.h was, incorrectly, redefining PATH_MAX which
causes a header order dependency in builtin-write-tree.c.  The fix
is to simply include <limits.h> directly to obtain the correct
definition of PATH_MAX.

Note that on Linux 2.2.14, PATH_MAX is define to be 4095.
(Solaris, Mac OSX, *BSD define it as 1024)
