fpclassify fix EntityManager: rename getExtant -> GetExtantAsHandles, fix its implementation+call site to avoid dynamic alloc/auto ptr, rename extant -> IsExtant vsnprintf2 -> sys_vsnprintf. remove printf.h (function is declared in sysdep header) use SUS/posix-ish strcasecmp instead of defining that to the windows-only stricmp add cppdoc for ia32/cpu This was SVN commit r5011.
