1# This Python script creates a full set of C++ C header files that
2# are missing on some platforms.
3#
4# Usage:
5#   mkdir cpp_c_headers
6#   cd cpp_c_headers
7#   python generate_cpp_c_headers.py
8#
9# The files created by this script are in the directory:
10#   root/boost/compatibility/cpp_c_headers
11#
12# Supported platforms:
13#   Compaq Alpha, RedHat 6.2 Linux, Compaq C++ V6.3 (cxx)
14#   Compaq Alpha, Tru64 Unix V5.0, Compaq C++ V6.2 (cxx)
15#   Silicon Graphics, IRIX 6.5, MIPSpro Compilers: Version 7.3.1.1m (CC)
16#
17# Support for additional platforms can be added by extending the
18# "defines" Python dictionary below.
