add set -e to the build-mingw scripts to catch possible regressions.

and SDL_Mixer are needed and are a lot harder to build.

expected.

According to David Turner, “it should be the only thing that NDK users
should be testing again.”

This is useful when doing several asserts in one loop, for instance: there
isn't always a way to deduce the loop index from the assert failure, so
these macros allow the user to give more context information.

we do not care about.

CPPUNIT_ASSERT_EQUAL(a, b) “expects” the value “a” and fails if “b” is
different. The logic seems backwards to me, but matching CppUnit’s
output is important so I’m doing the same in LolUnit.

and slightly tweak the API syntax.

CppUnit is really too large for our needs, would require to be precompiled
for many platforms, in all combinations of debug and release modes, with
additional variants for libstdc++ versions. We replace it with our own
lightweight implementation, LolUnit. Good riddance.

so that it builds properly.
