The only problem I can see is that getcwd() is passed a fixed buffer size
which won't get reallocated if it's too small (the default is PATH_MAX
which should normally be enough), and there's no way to tell it to get as
much as it needs --- it always seems to use the size argument.  This could
be fixed by checking for an ERANGE and reallocating.  There's no record of
problems with real getcwd()s in the source, but I don't think it was used
at all till recently.  Currently configure doesn't even check for getcwd().
Does anyone know more?
