Kp 4041e3ba53 Test whether compiler can use PCHs it generates 
Current gcc requires a non-PIE cc1plus for working PCH support.  If the
chosen compiler is PIE, it will succeed in building the PCH, then fail
when trying to use it.

Kp 4afae87883 Remove -Wcast-align from default compiler options 
Per issue from MattWatt, gcc for Raspberry Pi warns about alignment
issues.

Per issue from kreator, clang warns about alignment issues on OS X.
However, it does not warn on x86_64-pc-linux-gnu.

GCC only warns when compiling for a target architecture that requires
alignment, so it does not warn for i686-pc-linux-gnu or
x86_64-pc-linux-gnu.

Using this warning would be nice, but since it only triggers on
architectures not maintained by active developers, it causes more
trouble than it may solve.

Alignment sensitive users will have to get by with software fixups until
an active developer begins targeting alignment sensitive hardware.

Kp f1021de448 Add SDL_NumJoysticks() to SDL library test 
Some builds of SDL lack joystick support.  Rebirth requires joystick
support in SDL, even if the user never connects a joystick.  Add a call
to SDL_NumJoysticks during the SDL test so that systems without SDL
joystick support fail the "usable library SDL" test.

Kp 001fdfff37 Add workaround for gcc-4.8 ref qualifier quirk 
In gcc-4.8, a member method with const lvalue and const rvalue methods
is ambiguous.

	$ cat t.cpp

	{
	public:
	    void a() const &;
	    void a() const &&;
	};

	A b();
	void c()
	{
	    b().a();	// fails in gcc-4.8, works in later
	}
	$ gcc-4.8 -Wall -Wextra -std=gnu++0x -O2 -c t.cpp
	t.cpp: In function 'void c()':
	t.cpp:11:8: error: call of overloaded 'a()' is ambiguous
	  b().a();

Kp 658102a868 Improve static_assert test 
Previously, SConstruct tested whether static_assert worked with trivial
constant expressions.  Extend the test to more complicated expressions
like the ones used in the program.

Replace the typedef based approach with an inline enum to avoid warnings
about unused local typedefs.

Allow use with compilers that lack working static_assert or that cannot
accept complicated expressions.  Add a non-checking definition that uses
the input parameter.  This prevents warnings when types or constants are
used only for the static_assert.
