> Looking at the standard, there are actually 3 ways to define a char:
> * char
> * signed char
> * unsigned char
> There are no specificatoins regarding what "char" will be interperted as either "signed char" or "unsigned char". This is left to the OS/Compiler to choose.
> Solaris: int8_t --> char
> Linux: int8_t --> signed char

> char - type for character representation which can be most efficiently processed on the target system (has the same representation and alignment as either signed char or unsigned char, but is always a distinct type). Multibyte characters strings use this type to represent code units.
