* The following bug is in all snapshots starting
* from April 18.  I have only tested this on Alpha linux,
* and with FFECOM_FASTER_ARRAY_REFS set to 1.
* 
* Run the following through g77:
* 
      subroutine a
      character*2 string1
      character*2 string2
      character*4 string3
      string1 = 's1'
      string2 = 's2'
c
c the next 2 lines are ok.
      string3 = (string1 // string2)
      call b(string1//string2)
c
c this line gives gcc/f/com.c:10660: failed assertion `hook'
      call b((string1//string2))
      end
* 
* the output from:
* 
* /usr/local/egcs-19990418/bin/g77 --verbose -c D.f
* 
* is:
* 
* on egcs-2.93.19 19990418 (gcc2 ss-980929 experimental) (from FSF-g77 version 0.5.24-19990418)
