Hi,While testing gnulib I noticed that tfind on cygwin is defined like: void *tfind (const void *, void **, int (*) (const void *, const void *)); But POSIX requires [1] (*): void *tfind (const void *key, void *const *rootp, int (*compar) (const void *, const void *)); For programs written expecting the POSIX prototype, there will be many warnings that 'rootp' has it's const qualifier discarded.

Thanks for the report. tfind() and friends are supplied by newlib. I will look into what exactly to report there and/or send a patch there. It appears a bit more from that POSIX version needs implementation.
