Building nco: changes in Cygwin break linking

[Mark Hadfield]

Hello all

I am trying to build NCO version 2.8.0 from source 
(http://nco.sourceforge.net/). I have Windows 2000 SP4 with an 
up-to-date, reasonably complete Cygwin environment (cygwin 1.5.5-1, gcc 
3.3.1-3, etc). I use the usual "./configure, make" process. The build 
fails to produce executables, with output like this

/bin/bash ../../libtool --mode=link cc  -g -O2 -ansi  -L/usr/local/lib  
-o ncwa.exe  ncwa.o libnco.la -lnco -lintl -lm -lC -lnetcdf
cc -g -O2 -ansi -o ncwa.exe ncwa.o  -L/usr/local/lib ./.libs/libnco.a 
-L/usr/lib /usr/local/lib/libnco.a /usr/lib/libintl.dll.a 
/usr/lib/libiconv.dll.a -lC -lnetcdf

Info: resolving _optarg by linking to __imp__optarg (auto-import)
Info: resolving _optind by linking to __imp__optind (auto-import)
collect2: ld returned 1 exit status

When I followed exactly the same steps with exactly the same source on 
14 Aug 2003 I did not encounter this error. IIRC, I had an up-to-date, 
reasonably complete Cygwin environment then. So I presume that the 
problem is caused by the installation of a newer version of some Cygwin 
software component in the meantime.

Any suggestions on how to diagnose & solve the problem?
