[boost] [program_options] Darwin failure help?

From: Vladimir Prus (ghost_at_[hidden])

The program options library now fails a single test on Darwin, with this 
output:

../libs/program_options/test/parsers_test.cpp(205): fatal error in 
"call_test_main": test p.options.size() == 1 failed

*** 1 failure detected in test case "call_test_main"

The code in question is:

    putenv("PO_TEST_FOO=1");
    parsed_options p = parse_environment(desc, "PO_TEST_");

    BOOST_REQUIRE(p.options.size() == 1);

So, it seems that after "putenv", the string is is not available in the 
'environ' variable. The variable is declared like this:

#if defined(__APPLE__) && defined(__DYNAMIC__)
#include <crt_externs.h>
static char** environ = *_NSGetEnviron();
#else
extern char** environ;
#endif

The Darwin-specific conditinal was sent by Michael LaSpina, so I don't know 
what it really does, and so don't know why the test fails. I'd appreciate any 
suggestions.

Thanks in advance,
Volodya
