[Gcl-devel] Re: time in gcc to call a pointer to a function

[Camm Maguire]

Greetings!  Still looking into this, but it does appear that the
example I sent had some gcc code elimination.  If so, this still
leaves the issue of mutual recursion -- how important is this?  what
if function calls are somewhat slowed to attain it -- how much would
be worth it if any?

Take care,
