[kaffe] error about path_separator and file_separator

[kang shuo]

If I do not define __unix__ macro in my config.frag alias, it will
appear error message according to include/system.h :
##########################################
Error: Separators undefined for this system
##########################################

If I defined it, the error message will be :
