[PATCH 21.5] Newer coreutils doesn't like 'head -1'
Without this patch, I get the unhelpful:
Compiler version: detection failed (please report this)
in my Installation file, because on my system, coreutils-5.3.0
cleverly produces the following error to the command 'head -1':
head: `-1' option is obsolete; use `-n 1'
Try `head --help' for more information.
(This particular error is generated only on some systems, based on
whether or not coreutils thinks you should be POSIX-conformant.)
ChangeLog addition:
2005-03-23 Vin Shelton <acs(a)xemacs.org>
* configure.ac: Don't use head -1 due to over-zealous coreutils
complaints.
