VS2012

VS probably determines that since the condition is zero, therefore false, it does not output "lalala" and thus the block produces an empty string.

Probably just a scheme by MS to pass off an invisible newline character and sow discord.

Another thing I noticed:

const char* AXNAME[HYP_DIMS] = 
{
"x",
"y",
//"/",
//"tc",
"z",	//<-- valid in vc9
//"/",
//"/",
//"Vd",
//"t"
};

Is valid in vc9, but complains in gcc. I think that's how I noticed it, I don't remember, or maybe I ported it to linux and remembered that it should be wrong.

This also compiles on MSVC2012 on Windows XP:

	ovaldown |= ( (((HASHINT)case10)<<backbin) ,1);
	//ovaldown &= HASHCROP( ~HASHROTR( (((HASHINT)case8)<<bin) ,1) );
	ovaldown &= HASHCROP( ~( (((HASHINT)case8)<<backbin) ,1) );

But not on Mac XCode.
