#49 ref_soft: printf conversions.

[Juha hartikainen]

All of the printf style conversions are bad. They should
have been left as they were, but instead they were
converted to pascal string routines (using all kind of
nasty stuff as PChar typecasts, StrToInt, StrToFloat,
etc, etc.). For example sys_printf and sys_error places
in sourcecode are all wrong. Those should be reversed
as they were originally.
