Makes sense. The GDB build uses a c++ compiler. If you define strsignal as above, c++ assumes it's a C++ symbol, so its name gets mangled per the C++ mangling rules. Given the symbol is a plain C symbol, you'd have to specify this explicitely, i. e. extern "C" char *strsignal (int __signo); Anyway, this needs fixing in the system header. There's a matching thread on the newlib mailing list addressing this problem.
