Interesting dwarf-2/shared lib problem.

Looks like lbasename() in libiberty/lbasename.c is failing.  The
IS_DIR_SEPARATOR macro isn't being defined for __CYGWIN__ so when we've
compiled something with dos style paths...you get the picture.  I fixed it
in our source but someone might want to ponder this....
