New patch file with Falk's documentation correction fixed (GNU math libraries
- -> GCC libc math libraries) attached. Thanks Falk.
- -T
PS (again): This patch is meant to be applied directly against the current
tree (i.e. the tree that only contains the original alpha-ieee.dpatch file I
submitted and has not any of the subsequent patches I submitted applied).
