Thanks to both Dirk and Thomas for this portability fix.
I've pushed it now, with a few minor changes:
* Delete trailing whitespace
* Add include of "compat.h" from strcasestr.c
* Use original commit message from Dirk
Dirk, the commit message you sent with version 1 of the patch was
perfect. When you send followup patches, please leave a good commit
message as the initial content of the email. Then add any explanatory
text, ("v.3 of this patch...", "Please test..."), in the email *after*
the "---" separator (just before the diffstat). That way it won't become
part of the commit message and our indelible history.
For now, I manually touched things up, but it would be nice to not have
to do that in the future.
Thanks!
-Carl
