stdio: remove a layer of indirection in GetC/PutC We use zasm's ability to use labels in .equ directive. We didn't do it before because for a while, we were in between scas and zasm (scas was used in automated tests) so we needed to use the lowest common denominator: zasm doesn't have macros and scas can't use labels in .equ directives. This forced us to add this layer of indirection. But now that we are completely cut from scas' dependency, we can use this nice zasm's ability. 2019-11-05 01:55:12 +11:00			`.equ STDIO_GETC padGetC`
