lib/tmpfile.c and lib/tmpdir.c give compilation errors on MSVC 9,
because PATH_MAX is not defined.
Also, mingw defines PATH_MAX in <limits.h>, but to a wrong value (259
instead of 260). Same mistake as on HP-UX.
This fixes it:

pathmax: Support for native Windows.
* lib/pathmax.h (PATH_MAX): Define to 260 on native Windows.
