libksba-1.0.5 build issues

[Nelson H. F. Beebe]

Build attempts of libksba-1.0.5 failed on several platforms in my test
lab with these errors:

"visibility.c", line 322: void function cannot return value
"visibility.c", line 444: void function cannot return value
"visibility.c", line 558: void function cannot return value
"visibility.c", line 575: void function cannot return value
"visibility.c", line 665: void function cannot return value
"visibility.c", line 832: void function cannot return value
"visibility.c", line 848: void function cannot return value
"visibility.c", line 906: void function cannot return value
"visibility.c", line 992: void function cannot return value
"visibility.c", line 1095: void function cannot return value
"visibility.c", line 1103: void function cannot return value
"visibility.c", line 1179: void function cannot return value
"visibility.c", line 1186: void function cannot return value

Here is one example:

void
ksba_ocsp_release (ksba_ocsp_t ocsp)
{
  return _ksba_ocsp_release (ocsp);
}
