hdf5/test/links_env.c
Vailin Choi 0c589bf7b5 [svn-r19781] Fix for bug #1930:
1) Move the test for H5D_EXT_PREFIX in links.c to a separate file: links_env.c
2) links_env.c will be used by testlinks_env.sh to test for the environmental
   variable H5D_EXT_PREFIX in searching for the external linked file.
