I've repeatedly run into the problem where a private gcc 4.3 or? 4.5 frontend built on one Solaris machine and then run on another fails
because the second doesn't have libiconv but the first did. I have since carefully patched all the libiconv use out.
(not to mention the gmp/mpfr/mpc dependencies...)

It *appears* but I didn't confirm that all frontends pull in libcpp and libiconv, but I haven't fully looked into it.
