"""Build the include server module.
The version number should be passed to this script through the environment
variable DISTCC_VERSION. Also, the CPPFLAGS of the Makefile must be passed
through the environment. This is how we figure out the locations of include
directories. SRCDIR must be passed as well; it explains where to find the C
sources and the include_server directory of Python source files and C
extensions. Because SRCDIR is appended to build location and we don't want to
end up outside this location through a relative SRCDIR path with '..'s, SRCDIR
is absolutized.
