Tanay: are you not compiling with gcc -Wall -Werror?

(see my earlier message, just create a file config.mak containing

  CFLAGS += -Wdeclaration-after-statement -Wall -Werror

)

OK, it seems I got convinced too quickly by Junio ;-). The function
produces a char * that can be modified, but it also receives a value,
and the function should keep the "const" to allow passing "const char
*".
