No, the only difference between g++ and gcc compile for the affected files
is this warning from g++
cc1plus: warning: "-Wmissing-declarations" is valid for C/ObjC but not for
  C++
When I remove "-Wmissing-declarations" from the compile, no warnings at all,
or rather none for the files that contain #ifdef HAVE_BIGNUM

The darwinports' patched files tend to be very close to FreeBSD sources, and
that is good for OS X.  It is getting easier to compile software on the Mac
that compiles on FreeBSD with only minor changes to configure.  The problem
is primarily (in my experience) with differences in the linker parameter
names and the fact that Apple's libtool is very much non-standard and will
not recognize directives that GNUlibtool does.  The reverse is also the
case.

I am still seeing problems with cpan and cpanplus caused by these
inconsistencies--problems I don't see on FreeBSD.
