- Subject: PATCH: Fix libcpp configury/portability issue
Redefinding a macro, that is, #defining a macro which already has been
defined, will result in a build failure in later stages of building GCC,
so let's #undef said macro before.
Built on i386-unknown-freebsd4.10 with an "interesting" configuration
in a slightly older tree (since current mainline doesn't bootstrap for
completely unreleated reasons).

* internal.h (HAVE_ICONV): #undef, before redefining.
Okay to apply?
Gerald
