GCC auf Cygwin auf Version 5.4.0 aktualisiert. cmath erzeugt Fehler

Question

Also habe ich gerade meine gcc-Installation auf Cygwin von v5.3.0 auf v5.4.0 aktualisiert. Ich habe sichergestellt, dass ich auch den gcc-core updaten kann. Nun, wenn ich versuche, einen sehr einfachen Code, den ich die folgenden Fehler zu kompilieren:

ich nicht ganz versucht habe, Cygwin zu löschen und neu installiert alles, da ich, dass ein wirklich schlechten letzten Versuch betrachten. und ich denke wirklich nicht, dass das Editieren von cmath, um all diese "using" s zu entfernen, eine gute Idee wäre, da dies zu unvorhersehbarem Verhalten oder mehr Kompilierungsfehlern führen könnte. Also, was ist falsch ?

Answer 1

den Vorschlag @matzeri Versuchen: nur cygwin-devel

genau dieses auch gleiche Fehler Got installieren, wenn sie versuchen YouCompleteMe, zu bauen, der die Boost-Bibliothek zu erstellen versucht. Auch GCC 5.4.0 - installiert buchstäblich vor 10 Minuten. Die Installation von cygwin-devel hat diesen Fehler für mich behoben.

Leider, ich habe gerade ein neues über LONG_BIT definition falsch zu sein, aber das ist eine andere Frage ...
