Oops, that did not work. autoconf >= 2.60 supports multiline replacements
in AC_SUBST, but 'automake' and 'make' don't. I've reverted the commit and
done this instead:
2008-10-17 Bruno Haible <[EMAIL PROTECTED]>
Avoid gcc warnings because of #pragma GCC system_header on older gcc.
* lib/arpa_inet.in.h: Encloses reference to PRAGMA_SYSTEM_HEADER so
that it gets activated only for gcc >= 3.0.
* lib/dirent.in.h: Likewise.
* lib/errno.in.h: Likewise.
