无法在cygwin下编译GTK应用程序

Question

我正在尝试在Cygwin下编译Scintilla / SciTE。

编译器出现以下错误：

Scintilla / gtk

/usr/lib/gcc/x86_64-pc-cygwin/7.4.0/include/c++/tuple:1652:70: error: use of deleted function ‘LexerCPP::SymbolValue::SymbolValue()’
     second(std::forward<_Args2>(std::get<_Indexes2>(__tuple2))...)
                                                                  ^

Scite / gtk

    SciTEGTK.cxx:2737:3: error: ‘kill’ was not declared in this scope
    kill(-pidShell, SIGKILL);
    ^~~~

和

    SciTEGTK.cxx:5299:5: error: ‘usleep’ was not declared in this scope
    usleep(50000);
    ^~~~~~

这是Cygwin的更大问题吗？还是我缺少什么？
