I think the underlying issue here is that C99 is not officially
incorporated in C++03. But I don't honestly remember the precise
situation here.

The file to look at is qpid/sys/IntegerTypes.h which selects which
version of the stdint.h headers to use - you might get some idea from
the Visual Studio bits, which also don't support these C99 definitions
in earlier versions and so manually define some of these macros.

Bear in mind that the OS and compiler versions you are using are not
even supported by Red Hat any longer, so the sooner you move to RHEL6
the better off you will be.
