hdf5/test/external.c
Bill Wendling bfd983e7f4 [svn-r3770] Purpose: 
Update
Description:
    Changed includes of the form:

            #include <hdf5_file.h>

    to

            #include "hdf5_file.h"

    so that gcc can pick them up easier without including the system
    header files since we don't care about them.
Platforms tested:
    Linux
