As we all know, included files that are expressed in relative terms rather than
absolute (full path) terms are all relative to a set of 'include' paths. These
paths are defined as ...
 
  ** The directory in which the executing program resides.
  ** The list of directories specified in the EUINC environment variable.
** The directory ${EUDIR}/include, where EUDIR is the environment variable
  that specifies where Euphoria was installed.
 
What would be useful, is a way to specify in the include file name that we want
it relative to the file which is doing the including. For example's sake, let's
use the symbol "^" to represent the including file's directory. Then in the case
you mention one could do this ...
 
  ==== FILE_ZERO.EX ====
  include ..\file_one.e  -- one level up from 'here'
 
 
  ==== FILE_ONE.E ===
  include ^\file_two.e  -- same level as FILE_ONE.E
 
IN my case, with Win32lib I'd like to code ...
 
  === WIN32LIB.EW ===
  include ^/w32keys.e  -- same level as *this* win32lib
  include ^/w32alloc.e -- same level as *this* win32lib
  ... etc ...
