configure fails when checking for 'designated initializers' on NSK.
My patch (but I don't beile this is the right spot to fix this):

I did a simiral patch for source4/configure, but as that does get generated, it doesn't persist. Here it goes anyway:

Baseline is that configure would need to check with "-Wc99lite" to work properly on NonStop TNS/E machines (the compiler on the older nonStop TNS/R machines doesn't have that switch nor the features that go along with it)
