Another error at ext/curses.

have_func() in extconf.rb doesn't work correctly.
Even though testing symbol doesn't exit, cc's exit code is zero.

  $ cat conftest.c
  int main() { return 0; }
  int t() { wresize(); return 0; }

  $ cc -brtl -bI:/home/kubo/src/ruby-1.8.2/ruby.imp -bM:SRE -T512 -H512 -eInit_$(TARGET) -oconftest -I/home/kubo/src/ruby-1.8.2 -I../../.  -g conftest.c  -L"/home/kubo/src/ruby-1.8.2"  -lcurses -ltermcap  -lruby-static -lcurses -ltermcap  -ldl -lcrypt -lm   -lc

If '-eInit_$(TARGET)' is not set, its exit code is non-zero as expected.

  $ cc -brtl -bI:/home/kubo/src/ruby-1.8.2/ruby.imp -bM:SRE -T512 -H512  -oconftest -I/home/kubo/src/ruby-1.8.2 -I../../.  -g conftest.c  -L"/home/kubo/src/ruby-1.8.2"  -lcurses -ltermcap  -lruby-static -lcurses -ltermcap  -ldl -lcrypt -lm   -lc
