dnl extra magic check for netinet/{ip.h,tcp.h} because on irix 6.5.3
dnl you have to include standards.h before including these files
AC_DEFUN([CHECK_NETINET_IP_AND_TCP],
[
AC_CHECK_HEADERS(standards.h)
for i in netinet/ip.h netinet/tcp.h; do
cv=`echo "$i" | sed 'y%./+-%__p_%'`
AC_CACHE_CHECK([for $i],ac_cv_header_$cv,
[AC_PREPROC_IFELSE([AC_LANG_SOURCE([[
#ifdef HAVE_STANDARDS_H
#include <standards.h>
#endif
#include <$i>
]])],
[eval "ac_cv_header_$cv=yes"],
[eval "ac_cv_header_$cv=no"])])
ac_res=`eval echo \\$ac_cv_header_$cv`
if test "$ac_res" = yes; then
ac_tr_hdr=HAVE_`echo $i | sed 'y%abcdefghijklmnopqrstuvwxyz./-%ABCDEFGHIJKLMNOPQRSTUVWXYZ___%'`
