Re: float4 regression test failed on linux parisc

Tom,

The issue is with a select 'Infinity'::float4/'Infinity'::float4; which should return NAN.  without the cast I get the

overflow message from CheckFloat4Val with the cast I get NAN (as expected). How about testing for isnan() inside 
CheckFloat4Val (just for PARISC / Linux)? 

I am trying to get this system working for the buildfarm as there are NO other HP PARISC system on the farm.

Jim
