unable to build hpcboot

I can't build hpcboot anymore since the free/dealloc changes:

Linking...
libsa.lib(winblk.obj) : error LNK2019: unresolved external symbol dealloc referenced in function winblkopen
libsa.lib(ufs.obj) : error LNK2019: unresolved external symbol dealloc referenced in function ufs_open
..\compile\ARMRelease/hpcboot.exe : fatal error LNK1120: 1 unresolved externals


The attach patch seems to solve it, but I'm wondering... is this the right
thing to do?
