For porting 'fpurge', you need some insight into the internals of a FILE
stream on the particular platform.

The fpurge function is best ported together with a couple of other
functions.

You find in   http://www.haible.de/bruno/gnu/testdir-stdioext.tar.gz
the documentation and implementation for all systems so far (from BSD
systems to QNX), and a test suite. The documentation/specification is
in the .h files.

To port this package:

  - Unpack the package, configure it. Try "make" and fix the problems.
  - Run "make check" to see the test results.
  - The recommended order of porting (from easy to harder) is:
    fbufmode, fseterr, freadable, fwritable, freading, fwriting,
    fpending, fpurge, freadptr, freadseek, freadahead.
