[svn-r4038] Purpose:
Code clean/bug fix
Description:
H5FL (free-list manager) code currently is taking an hsize_t as the size
of a memory block to allocate. On many machines, the size of an hsize_t
is greater than the size of a size_t, potentially leading to incorrect
memory allocations in rare circumstances.
Solution:
Changed hsize_t parameters and variables to size_t.
Platforms tested:
FreeBSD 4.3 (hawkwind)
