This bug is of same magnitude as the bug 14788 is. If the compiler developers assume that all compiler users are idiots throw that at /dev/nul. On the other hand if that warnings are enabled by default that's a bug in the user space headers and should be reported appropriately.
Those functions are used all throughout Wine without warning. Only 42 of them are causing a warning, and if anything, should be investigated.
If you feel otherwise, feel free to mark invalid. I wanted to make sure the issue was at least known.
