Check for individual features; for example, when the feature in
question is support for translators, you might want to check for the
function file_set_translator. This way, GNU tar will correctly detect
other systems that might support translators in the future but don't
provide a hurd.h file.
If you want to check for GNU/Hurd, use #ifdef __GNU__, but this should
only be done with a good reason, like when porting a program that uses
tests based on the operating system already.
Cheers,
