Description:
------------
This is a reference to PECL bug #16575
<http://pecl.php.net/bugs/bug.php?id=16575>.
Since intl will shortly be
part of core instead of PECL, I feel this bug belongs here. Here's my
addition to the issue:

This is due to intl/msgformat/msgformat_helpers.cpp being a C++ file
and GCC not handling that case cleanly. The exact error is specifically
due to GCC not linking to libstdc++. Which is, actually, kinda
reasonable since it's been invoked as a plain C compiler. Anyway, you
can get around the problem for now by adding
"/usr/lib/gcc/i686-apple-darwin9/4.2.1/libstdc++.dylib" (if you're
building with gcc-4.2) or
"/usr/lib/gcc/i686-apple-darwin9/4.0.1/libstdc++.dylib" (if you're
building with gcc-4.0, the default) to your LDFLAGS. That's right,
WITHOUT -l or -L. I wouldn't consider this a real solution, but a better
solution is pending further research into the subject.

Reproduce code:
---------------
$ CFLAGS='-arch x86_64' CXXFLAGS='-arch x86_64' LDFLAGS='-arch x86_64'
./configure --enable-intl --with-icu=/path/to/icu
$ make


Expected result:
----------------
Build complete.
Don't forget to run 'make test'.

$ 

Actual result:
--------------
Undefined symbols:
 "___gxx_personality_v0", referenced from:
     EH_frame1 in msgformat_helpers.o
ld: symbol(s) not found
collect2: ld returned 1 exit status
make: *** [sapi/cgi/php-cgi] Error 1
$
