hdf5/perform/benchpar.c
James Laird 8619af74a4 [svn-r11601] Purpose:
Added additional targets to build-all

Description:
Surveyed files to find out which ones are not built.
Added test/space_overflow and perform/benchpar to programs built with
--enable-build-all.
Discovered that tools/misc/pdb2hdf5 and tools/misc/h5import were
obsolete and deleted them.

Platforms tested:
mir, modi4, sol

Misc. update:
Update of release file and removal of --enable-pdb2hdf5 to follow.
