[netCDF #IWZ-281549]: netcdf 4.2 soname bump

Hi Orion,

> The soname version was bumped in 4.2-rc1 to 8.  Why?  It appears that it is
> completely compatible with version 4.1.3 as shown by the attached report.

I actually changed it back to 7.1.1 earlier today in our snapshot release 
(coincidentally
a little before you sent your question), because we decided to disable the 
diskless file
implementation, which was not finished and not ready for prime time.  To support
diskless files, a new constant had been defined in netcdf.h, NC_DISKLESS, as a 
flag to
nc_create(), which we thought had changed the interface to that function, 
requiring
bumping the soname version.

I may have been misinterpreting the meaning of "interface change", but it seems 
that
with the 4.2-rc1 library, you could write code that wouldn't link with a 4.1.3 
library,
due to the addition of the new mode flag.  In any case, you'll find that 
constant gone
in the current snapshot and the next release.
