The toolset was modified on my behalf. Below is an excert of the mail I
sent to justify the changes.

This happended to me when compiling boost.python because python forces the _XOPEN_SOURCE to 600. You need to fix the iotraits header file for this.

With the current toolset I am able to compile the whole boost libraries
(v 1.31.0) on my platform (OSF1, V5.1, alpha) and compiler (Compaq C++
V6.5-033 for Compaq Tru64 UNIX V5.1B (Rev. 2650)).

I just started downloading the current CVS snapshot to have a look at
this problem.
