For reference the given /sr/include/signal.h:
#ifdef __USE_MISC
/* Print a message describing the meaning of the given signal number. */
extern void psignal (int __sig, __const char *__s);
#endif /* Use misc. */
And libiberty/strsignal.c
#ifndef HAVE_PSIGNAL
void
psignal (int signo, char *message)

=> Probably related to -Wc++-compat
