I would very much prefer to see set_user_assembler_name first...

This excerpt from my math.h confirms that you need an underscore:

#if ( __WANT_LONG_DOUBLE_FORMAT__ - 0L == 128L )
#define __LIBMLDBL_COMPAT(sym) __asm("_" __STRING(sym) "$LDBL128")
#elif ( __WANT_LONG_DOUBLE_FORMAT__ - 0L == 64L )
#define __LIBMLDBL_COMPAT(sym) /* NOTHING */
#else
#define __LIBMLDBL_COMPAT(sym) /* NOTHING */
#endif
