Summary: inerger promotion of casted varargs

Initial Comment:
Sdcc doesn't perform the integer promotion for variable arguments which are explicitly casted. This is a nonconformity with the ISO C standard and is treated as an sdcc extension.

Sdcc should be conform to the ISO C standard in case the --std-cXX command line option is defined.

For reference see bug #1874922: "explicit typecast is ineffective for unsigned char parameter" at https://sourceforge.net/tracker/index.php?func=detail&aid=1874922&group_id=599&atid=100599 .

Request for help: I don't have ISO C89 standard (I have ISO C99), so I don't know if the requirements for integer promotion for variable arguments are same in both. Any help appreciated!

Borut
