representations of ELF types.
The ELF(3) API allows applications to request a conversion that is
`in-place', i.e., with source and destinations data buffers being
the same. However, the file and memory sizes of ELF sections that
have additional internal structure, such as those of type `Elf_Note',
or `Elf_GNU_Hash_Header', can be determined only known after the
type-specific headers that comprise the first few words in these
sections are read and translated.
Pass in the size of destination buffer to type translation routines
in "libelf_convert.m4" and have these routines return an error code
if the translated data would not fit inside the destination buffer.

been removed from the condition altogether.
The FP version broke profiling on powerpc due to invalid results.
Casting to double instead of float resolved the issue, but with
Book-E not having a FP unit, the non-FP version looked preferrable.
Note that even on AIM hardware the FP version yielded an invalid
value for s_scale, so the problem is most likely with the compiler
or with the expression itself.

* Quote '*', '?' and '['. While it may be more useful to expand them to
matching pathnames, this at least matches with the completion we do.
* '@' is a regular character for filenames. Some other shells do
@<hostname> completion but we do not.
* Prefix names starting with '-' and '+' with './' so they are not seen as
options.
The completer recognizes characters escaped with backslashes as being
literal parts of a word, and adds backslashes to avoid almost all
misinterpretation. In particular, filenames containing spaces can be
completed correctly.
For bug compatibility with the NetBSD version, the improved completion
function has a new name, _el_fn_sh_complete, and _el_fn_complete is
unchanged.

it to the imported revision of Clang. I do want to have a date in there,
