[bug-mailutils] New build system on cygwin

[d.henman]

Happpy new year to all.

Cygwin build update.

The new build system seemed to run fine.    

I did, however run into the following build problem:

---- 
/bin/sh ../libtool --tag=CC   --mode=link /usr/local/bin/gcc  -g -O2 
../mailbox/libmailutils.la -lintl -liconv  -o aclck.exe aclck.o  -lcrypt 
-lresolv  -lpthread -lgdbm
/usr/local/bin/gcc -g -O2 -o aclck.exe aclck.o  ../mailbox/.libs/libmailutils.a 
-L/usr/lib /usr/lib/libintl.dll.a /usr/lib/libiconv.dll.a -lcrypt -lresolv 
-lpthread /usr/lib/libgdbm.dll.a
