Subject: [PATCH] Fix for uClibc and gcc <= 4.8.2
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

getchar() is defined as a macro in uClibc. This hits gcc bug 58952 [1] for all
gcc version <= 4.8.2 and building boost/test fails:

./boost/test/impl/unit_test_main.ipp: In function 'int boost::unit_test::unit_test_main(boost::unit_test::init_unit_test_func, int, char**)':
./boost/test/impl/unit_test_main.ipp:194:18: error: expected unqualified-id before '(' token

To allow building boost/test with uClibc based toolchains with gcc <= 4.8.2 use
parenthesis for std::getchar.
