 I haven't been able to reproduce this using today's 3.1 sources.  (More at
 the end.)

 A few observations that probably make no difference to this PR:
 
 - I note that you configured your compiler for "sparcv9-sun-solaris2".
   Usually the final bit is a complete OS version, like 2.7 or 2.8.
 
 - Your system was reported as
     SunOS 5.7 Generic_106541-19 sun4u sparc SUNW,Ultra-2
   The one I used to test is
     SunOS 5.8 Generic_108528-13 sun4u sparc SUNW,Ultra-30
 
 - You mentioned you were using NFS and AFS.  My test was all local.
