for floats (currently only). On x86_64 uses built-in fp constants (in libtcc1.c) to avoid multiple anonymous instances. Also: win32/i386: use __alloca for big struct stack store - use new function int tok_alloc_const(const char*); - change alloca86.S to preserve EDX tccelf.c: fix a warning with 'roinf_use'
