are you sure ?
I had no problem linking octave to cyglapack-0.dll

$ cygcheck  /usr/bin/cygoctave-4.dll |grep lapack
     E:\cygwin64\lib\lapack\cyglapack-0.dll

looking at
  objdump -x  /usr/lib/liblapack.dll.a |grep cyglapack |

I see only refence to cyglapack_0_dll

May be you installed another /usr/lib/liblapack.dll.a ?

on 64 bit
$ /usr/bin/ls -l  /usr/lib/liblapack.dll.a
-rwxr-xr-x 1 marco None 1077988 Jan 10 22:55 /usr/lib/liblapack.dll.a

on 32bit
  $  /usr/bin/ls -l  /usr/lib/liblapack.dll.a
-rwxr-xr-x 1 marco None 1106656 Jan 11 07:08 /usr/lib/liblapack.dll.a


Regards
Marco
