# Increment sntp_configure_cache_version by one for each change to
# configure.ac or .m4 files which invalidates cached values from
# previous versions.
#
# If the change affects cache variables used only by the main NTP
# configure.ac, then only its version number should be bumped, while
# the subdir configure.ac version numbers should be unchanged. The
# same is true for a test/variable that is used only by one subdir
# being changed incompatibly; only that subdir's cache version needs
# bumping.
#
# If a change affects variables shared by all NTP configure scripts,
# please bump the version numbers of all three. If you are not sure,
# the safe choice is to bump all three on any cache-invalidating change.
#
# In order to avoid the risk of version stamp collision between -stable
# and -dev branches, do not simply increment the version, instead use
# the date YYYYMMDD optionally with -HHMM if there is more than one
# bump in a day.

AC_HEADER_STDC
dnl HP-UX 11.31 on HPPA has a net/if.h that can't be compiled with gcc4
dnl due to an incomplete type (a union) mpinfou used in an array. gcc3
dnl compiles it without complaint. The mpinfou union is defined later
dnl in the resulting preprocessed source than the spu_info array in
dnl /usr/include/machine/sys/getppdp.h:
dnl extern union mpinfou spu_info[];
dnl triggering the error. Our strategy is on HP-UX only, test for
dnl net/netmp.h, which is the file included by net/if.h that leads to
dnl getppdp.h. If it is present but can't be compiled, try adding
dnl a duplicate definition of mpinfou, which should then allow the
dnl following net/if.h and net/if6.h tests to proceed normally.
dnl Using net/netmp.h allows us to avoid polluting test results for
dnl net/if.h.
