[netCDF #ZQT-710878]: NetCDF Fortran install error: "error: Could not link conftestf.o and conftest.o"

Hello,

I'm not certain what the cyglto_plugin.dll library is, although it appears to 
be specific to cygwin.  A search on Google returns nothing specific, other than 
it is related to gfortran under Cygwin, but you already knew that.   This error 
doesn't appear to be related specifically to netcdf-fortran; are you able to 
compile other fortran programs?  If you provide the config.log generated by 
configure, I will take a look and see if anything else pops out.  

Alternatively, you might try the pre-built netcdf fortran libraries provided 
via the cygwin installer.  

I hope this helps,

-Ward
