Try configuring with --prefix=/user/gccfull
rather than --prefix=/user/gccfull/

The code in update_path recognizes the prefix in your directories, strips it, 
and passes @g++include/myg++ to translate_name instead of the correct
@g++/include/myg++

One fix is to guarantee that std_prefix as used in prefix.c never ends in a /.  A harder fix is to edit update_path to strip trailing slashes from 
std_prefix before it does the comparison.  Yet another fix is to guarantee that the string constructed by concatenation has a / between the G++ and 
the "include".  

But I think the best fix :-) is to change the demented scheme used by prefix.c to eliminate that whole @blah/blah and $blah/blah interface to 
translate_name.  It seems designed to allow repeated substitution (so that @G++/ gets replaced with @GCC/ gets replaced with $FOO/ gets replaced 
with $BAR/ ...) but that seems quite unnecessary and even undesirable.   (I could be wrong, of course...) If that's eliminated, a single layer of 
substitution can be better implemented by having the 'key' as a separate argument to translate_name.
(Or possibly the entire 'key' business could be eliminated outright, as I don't see what it's used for anyway!)
