+There is an implicit historical assumption from around Perl5.000alpha

 Ideally, we should create a new variable to hold the name of the executable
 linker program, probe for it in F<Configure>, and centralise all the special
 case logic there or in hints files.
 
 A small bikeshed issue remains - what to call it, given that C<$ld> is already
-taken (arguably for the wrong thing) and C<$link> could be confused with the
-Unix command line executable of the same name, which does something completely
-different. Andy Dougherty makes the counter argument "In parrot, I tried to
-call the command used to link object files and  libraries into an executable
-F<link>, since that's what my vaguely-remembered DOS and VMS experience
-suggested.  I don't think any real confusion has ensued, so it's probably a
-reasonable name for perl5 to use."

 "Alas, I've always worried that introducing it would make things worse, 
 since now the module building utilities would have to look for 
 C<$Config{link}> and institute a fall-back plan if it weren't found."
