>Description:
/* Demonstrates bug in egcs-2.91.66 on FreeBSD 3.2.  To see the bug,
   compile using:
  
          gcc -c token.c -g -Wall -O2 

   The bug is the warning:

     token.c:17: warning: `c' might be used uninitialized in this function

   egcs-2.91.60 on Solaris 2.6 reports this message twice.
