[svn-r9592] Purpose:

    Bug fix

Description:
    Re-work array of 'forward' pointers in a way that makes the PGI compiler
more happy.

Solution:
    Change from 'H5SL_node_t *forward[1]' to 'H5SL_node_t **forward' and
change how array of forward pointers is dealt with.

Platforms tested:
    Linux 2.4 (verbena) w/PGI
    FreeBSD 4.10 (sleipnir)
    Configuration not tested w/h5committest
