The problem with reallocf() is that there is not a prototype for it that I found. What's the appropriate header for a prototype for reallocf()? (It would seem to be stdlib.h, but it would need some kind of ifdef to only have it when posix (et.al.) was in use. Jeff: do you know how to conditionally include it appropriately?) As for the second problem ("free(s);" to "free((void *)s);"), gcc 3.4.4 says collate.c:183: warning: passing arg 1 of `free' discards qualifiers from pointer target type If it weren't for the very odd way that the beginning of the function is coded that allows the problem to be avoided, this would be best addressed with the cast to eliminate the warning. But given that the strdup() and free() are completely unnecessary, I have attached a different patch that removes the problem. I left out the cast for reallocf() since it should be fixed with a prototype. (There are two other files that also refer to reallocf().) A different approach would be to always include reallocf(), instead of only having it under posix and sys/linux, as then the condition on the prototype would not be needed.

This just silences the warnings. I am opposed to this patch. Better live with warnings until they can be properly fixed and do not try to play things down by hiding them away. Ralf
