I am a FreeBSD committer, and I recently ran into this issue too, since I am
working on an update of libc++ in the FreeBSD base system. As part of this
work, we attempt to recompile all ports with the proposed change (see [1]).
During such a recompile, we get many errors in ports that include pyport.h in
C++ mode, similar to (see [2]):

#define toupper(c) towupper(btowc(c))

I think Ronald's proposed workaround is fine, since messing with ctype macros
is risky in C++ mode. E.g. the libc++ <ctype.h> header explicitly undefines
all ctype macros, and replaces them with inline functions.
Additionally, the original issue mentioned in changeset 32950 [3] was fixed in
October 2007 for FreeBSD 8.x [4], and subsequently the fix was merged back to
FreeBSD 6.x and 7.x [5].
I'm adding an additional diff that corrects the __FreeBSD_version number
checks. This will also be submitted to the FreeBSD ports bug tracker.
