According to Thomas Klausner on 4/21/2008 4:46 AM:
| Hi!
|
| I don't have a DragonFly box myself, but apparently m4-1.4.11 doesn't
| compile on it.
Thanks for the report. Adding bug-gnulib, since this patch should be
applied there to affect multiple projects.
|
| One of the main DragonFly developers provided a patch, see
| http://leaf.dragonflybsd.org/mailarchive/users/2008-04/msg00044.html
|
| The patch is a patch against pkgsrc, I'll attach the resulting "real"
| patch against m4 to this mail.
It looks like the patch does two things - use the underlying __sreadahead
to implement freadahead (hmm, do any other platforms provide this
functionality already, and does DragonFly's implementation meet the
contract that we defined for our invention of freadahead?).
It also disables the fseeko replacement on DragonFly - why? The fseeko
replacement is used if the system fseeko is deemed to be buggy at
configure time; is the configure test guessing wrong, or is this patch
actually introducing a regression by overriding the correct configure test?

Don't work too hard, make some time for fun as well!
