Hi Alan,

the understanding is correct, it should be
libgnat-6.dll.a or libgnat.dll.a
However as

  $ gnatlink -v -shared hello
GNATLINK 6.4.0
Copyright (C) 1995-2016, Free Software Foundation, Inc.
gcc -c -mtune=generic -march=x86-64 -gnatA -gnatWb -gnatiw -gnatws 
/tmp/ada/b~hello.adb
/usr/bin/gcc.exe b~hello.o ./hello.o -shared -o hello.exe -L./ 
-L/usr/lib/gcc/x86_64-pc-cygwin/6.4.0/adalib/ -lgnat-6 
-Wl,--stack=0x2000000 -shared-libgcc
/usr/lib/gcc/x86_64-pc-cygwin/6.4.0/../../../../x86_64-pc-cygwin/bin/ld: 
cannot find -lgnat-6
collect2: error: ld returned 1 exit status
gnatlink: error when calling /usr/bin/gcc.exe

I suspect the ada package is incomplete, so I raised
the attention of the package maintainer.
