I could modify it to do it as Russ suggests, but there may be another
way. Autoconf archive has this


I could use this in our configure process. If a platform/compiler
supports __attribute__ it defines HAVE___ATTRIBUTE__ . Then in our code
we could simply do:

#ifndef HAVE___ATTRIBUTE__
#define __attribute__(Spec) /* Empty */
#endif /* HAVE___ATTRIBUTE__ */
