Yes, it's quite a bad idea to ship code with -Werror. Developping with
heavy-strong CFLAGS is good, shipping with them is always a bad idea as
gcc could evolve in a direction where it creates more warnings and cause
compilation problems with new gcc versions.

technically, the reason is explained in unistd.h:
/* The Single Unix specification demands this prototype to be here.
It is also found in <stdio.h>. */
#ifdef __USE_XOPEN
/* Return the name of the controlling terminal. */
extern char *ctermid (char *__s) __THROW;
#endif
So this won't be fixed as it's the intended way. Also note that there
is absolutely nothing wrong with redundant declarations in C as soon as
they are type-compatible. So it's quite a useless warning anyway.
