+If your system needs to link with -lPW to get alloca, but has
+rename in the C library (so HAVE_RENAME is defined), -lPW might
+give you an incorrect version of rename. On HP-UX this manifests
+itself as an undefined data symbol called "Error" when linking cp, ln,
+and mv. If this happens, use `ar x' to extract alloca.o from libPW.a
+and `ar rc' to put it in a library liballoca.a, and put that in LIBS
+instead of -lPW. This problem does not occur when using gcc, which
+has alloca built in.
