Fix compiler warnings on Cygwin and Mac OS X.

  • Don't use PIE/PIC on Cygwin/Darwin unless specified as these platforms don't support it.
  • Cleanup warnings for 'make check' build.
  • Fix the type issue for getsockopt calls.
  • Fix enum warnings in Yahoo libs on Mac OS X.
  • Property mode set to 100755
