I recall having tried some earlier version on my old HPUX dinosaur,
and it worked, but this one doesn't compile:

float.c: In function `float4in':
float.c:240: error: `HUGE_VALF' undeclared (first use in this function)
float.c:240: error: (Each undeclared identifier is reported only once
float.c:240: error: for each function it appears in.)

As far as I can find, that symbol doesn't appear anywhere in the
system headers on this platform.

FWIW, I did get a successful build and core regression test run on
NetBSD 8.99/aarch64.

regards, tom lane
