There is some chance that 5268 is fixed by
http://sourceware.org/ml/libc-alpha/2013-06/msg00919.html
but it doesn't fix 14551. I didn't develop the denormal fixes in
response to any particular bugzilla, but rather from simply browsing
the source when making changes for little-endian support, and noticing
nastiness. In fact, these bug fixes are a distraction from my main
aim, which is little-endian support.
Do you really have to file a bugzilla to fix bugs around here?
