Error building astrometry.net on Fedora rawhide

[Mattia Verga]

When trying to build astrometry.net on Fedora rawhide I get the error

permutedsort.c:125:2: error: non-floating-point argument in call to function '__builtin_isnan'
  COMPARE(f1, f2, <, >);
...
permutedsort.c:131:2: error: non-floating-point argument in call to function '__builtin_isnan'
  COMPARE(f1, f2, >, <);

See https://kojipkgs.fedoraproject.org//work/tasks/4974/12574974/build.log

Building on Fedora 23 works fine, so I think some other package upgrade in Fedora broke astrometry.net.
How can this error be fixed?

Thank you

Oh, never mind, that error message is completely correct -- there was a bug in that code.

Here's a new release with the fix.
