PATCH: pws-19: another configure tweak

[Peter Stephenson]

This is necessary when the source and build trees don't coincide.

By the way, it looks like mapfile using mmap() doesn't write the file
properly on HPUX, probably the file doesn't get extended properly first.
I'll have to look at that.

Also, I'll be away for a few days from tomorrow until Monday.

No real wonder.  This was there at some stage, though.
