   When I specify a dependency in another directory, I usually want
   it fetched from the SCCS directory under that other directory into
   that other directory.

   With the code as delivered in 3.63, a dependency of '../hdr/foo.h'
   will create './foo.h' from '../hdr/SCCS/s.foo.h'.  Not what I want at all.

   A dependency of '../hdr/foo.h' should create '../hdr/foo.h'
   from '../hdr/SCCS/s.foo.h'.

   See #ifdef _MODCOMP in the following copy of 'default.c' for my
   fix for this.  The first occurance is the fix, the rest have to
   do with our compiler names for FORTRAN and PASCAL.

   There may be a better way to do this directly from the get command
   but this worked so I quit fixing it.
