g++ 4.2 rejects a quoted string constant, where the function prototype has char *. It says warning, but the warning is fatal, even without -Werror. -fpermissive doesn't let it pass. info g++ lists an option -fconst-strings, but that option has been removed. What is expected as a replacement for current source code with 1000's of string constants, which up to now worked with char * prototype? Tim Prince
