>Description:
In the process of developing a FEniCS package, I ran into problems building qt4-lib on RHEL 5.3.

The attached patch file contains a workaround with comments.  I'm not 100% sure it's safe to assume that the constants pulled from futex.h will remain unchanged, so it might be a good idea to wrap the patch with a kernel version check.  This might be easier in the package Makefile using ${OS_VERSION} than it is in the source file.

>How-To-Repeat:
Try to build qt4-libs on RHEL 5.3.

 This can be closed.  We no longer run RHEL 5 and the package builds on 6 
 & 7.
