[Interest] Problem Building QT 5.0 RC1 on Redhat Enterprise

[Christoph Cullmann]

Hi,

we need to build Qt5 on still supported RedHat Enterprise Release 4.

After building enough other new stuff needed as dependencies on such a machine, we run into this in WebKit2:

Platform/unix/SharedMemoryUnix.cpp: In static member function 'static WTF::PassRefPtr<WebKit::SharedMemory> WebKit::SharedMemory::create(size_t)':
Platform/unix/SharedMemoryUnix.cpp:110:66: error: 'O_CLOEXEC' was not declared in this scope

Problem is O_CLOEXEC is only around for newer kernel versions than in this distro (and newer shipped headers).

Any patch chances?

Greetings
Christoph
