/*
 * HISTORY
 * 	Allow selection of macro definitions only.
 * 	That is, provide a compatibility layer that requires no library
 * 	functions only macro definitions. This is enabled by defining the
 * 	macro DOWNHILL_NO_FUNCTIONS.
 * 	[1997/06/23  12:12:05  tbartley]
 *
 * 	Add uio calls: readv, writev.
 * 	Make libdownhill installable.
 * 	Put include guards around stdlib.h.
 * 	[1997/05/21  07:35:49  tbartley]
 * 
 * 	Conditionalise the definition of MAXPATHLEN. ON WIN32 _MAX_PATH is only
 * 	(at most) 260. Since we have to interoperate with machines where the
 * 	path may be much longer than that and also becuase MAXPATHLEN has been
 * 	used throughout ODE as a generally large buffer size we allow this
 * 	macro to be predefined. We set it in Makeconf to 2048.
