Hi Kent,

First, apologies for not replying to this question earlier.  We were all
out of town at a meeting last week and came back to a large backlog of
support questions ...

I'm forwarding your message to Steve Emmerson, who has successfully
built and tested netCDF 2.4.3 on NCAR's J90.  He'll be looking at it in
the next day or two, to see if we can duplicate the problem here or see
what's wrong.

I've appended a copy of the reply I sent on Tuesday, 21 January, to the
address

   "Kent F. Milfeld" <address@hidden>

I'm sorry if you didn't get it, but we never received a "bounce" message
or any other indication that the mail failed.

Please let me know if you don't get this one :-).

 We discuss a fix in our document "Known Problems with the netCDF
 Distribution", although this problem is really a Cray C++ compiler bug.
 The workaround description is at

     http://www.unidata.ucar.edu/packages/netcdf/known_problems.html#cray-cxx

 and a previous message/reply that gives more details about the problem
 and workaround, in case you're interested, is available at

     http://www.unidata.ucar.edu/glimpse/netcdf/2009

 Errors in config.log may be ignored, since they are merely side-effects
 of the "configure" script trying to determine the correct configuration
 by compiling various test programs and noting compiler/linker errors.
