The checks for obsolete isinf(double) and isnan(double) are not run on
freebsd. Apparently,
the checks in acinclude.m4 need to be run on freebsd as well. Maybe
the checks should run almost
everywhere?
Yes, maybe. I didn't realise those functions were so widespread, but
if they are I'm amazed more people weren't yelling about
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=48891
The problem wasn't introduced by my change but earlier by Jonathan. I
added hpux to the list
of systems with obsolete defines. The default is to assume there are
no obsolete defines.
I think it should be harmless to run the checks on all systems. If
they don't have obsolete defines we'll detect that. If they do things
will start working.
