The attached patch fixes a stage1 build error compiling genautomata.c on hpux.  
We need to test for obsolete

individually for isinf and isnan on hpux11
since only isnan has an obsolete XOPEN declaration.

Tested on hppa2.0w-hp-hpux11.11.

Also tests OK on x86_64-linux (with glibc 2.22).

Okay for trunk?

Yes, OK, thanks.
